This commit converts the LaCie d2 Network platform to the Device Tree.
All devices except LEDs are converted, because the LED code needs a
non-LED GPIO to be set to a given value for the LEDs to work, and this
cannot yet be easily represented in DT.
Also, references to the LaCie Big Disk Network platform are lost,
because this platform apparently has exactly the same hardware support
as the LaCie d2 Network, so their Device Tree files would be
identical.

This commit converts the RD-88F5182 platform to the Device Tree. All
devices except the PCI are converted to the Device Tree.
It is worth noting that:
* The PCI description for the DT case is kept in board-rd88f5182.c.
* The existing non-DT support in rd88f5182-setup.c is kept as is, in
order to allow testing of a given platform in both DT and non-DT
cases. It will ultimately be removed, once we no longer care about
non-DT support for Orion5x.

This commit switches the Orion5x platforms described through DT to use
a DT-defined interrupt controller and timer.
This involves:
* Describing in the DT the bridge interrupt controller, which is a
child interrupt controller to the main one, which is used for timer
and watchdog interrupts.
* Describing in the DT the timer.
* Adding in the DT the interrupt specifications for the watchdog.
* Selecting the ORION_IRQCHIP and ORION_TIMER drivers to be compiled.
* Change board-dt.c to no longer have an ->init_time() callback,
since the default callback will work fine: it calls
clocksource_of_init() and of_clk_init(), as needed.
* Implement a multi-IRQ handler for non-DT platforms in
mach-orion5x/irq.c.

Until the previous commit, the Orion5x clocks were not described in
the Device Tree. Now that they are described in the Device Tree, we
can replace the manual 'clock-frequency' property in the UART nodes
by a nicer 'clocks' reference in those UART nodes.
This commit consequently removes the 'clock-frequency' property from
the LaCie edmini_v2 board, which is at this point the only Orion5x
board converted to the Device Tree.

This commit switches the Orion5x Device Tree files to use the DT
representation and probing for the mvebu-mbus driver. The changes are
mainly:
* Re-organize the DT to follow the same organization as the one used
on Armada 370/XP, which is needed for mvebu-mbus to work: a
top-level soc { ... } node, which corresponds to the MBus bus, and
a sub-node internal-regs { ... } for all peripherals whose register
sit only in the "Internal Register Window". This change re-indents
by one level the definition of all nodes in the Device Tree, which
explains the large change.
* Use custom functions orion5x_dt_init_early() and
orion5x_dt_init_time() instead of orion5x_init_early() and
orion5x_timer_init() as we now want the MBus driver to be probed
from the Device Tree. We still use the old-style timer
initialization, but that will be changed in a followup commit.

The interrupt controller node was located outside of the ocp@f1000000
node, which doesn't make much sense: like any other device, the
interrupt controller has registers located in the "Internal Registers
Window", so it is much more logical to have it under the ocp@f1000000
node.
It is even more important as we are going to move Orion5x to use the

Back when the Armada 370 and Armada XP initial support was introduced,
the only way to pass the clock frequency to the of_serial driver was
through a clock-frequency Device Tree property.
Thanks to 0bbeb3c3e8 ('of serial port
driver - add clk_get_rate() support'), it is possible to use the
standard 'clocks' DT property to reference the clock used for a
particular UART controller. This clock is then used by the of_serial
driver to retrieve the clock rate.
This commit modifies the SoC-level Device Tree files of Armada 370,
Armada XP, Armada 375 and Armada 38x to use this possibility. Since
there is no gatable clock for the UART controllers, we simply
reference the TCLK, which is the main SoC clock for the peripherals.

However, this commit forgot to define the I2C bus frequency, which
leads the i2c-mv64xxx to fail probing, as it cannot calculate the baud
rate multiplier/divisor to derive the I2C bus frequency from the core
SoC frequency. It makes audio completely unusable, as the I2C bus is
not probed, and therefore the audio codec is not probed either.

Until now, the Armada XP GP was relying on the bootloader setting the

The mvebu-devbus driver had a serious bug, which lead to a 8 bits bus
width declared in the Device Tree being considered as a 16 bits bus
width when configuring the hardware.
This bug in mvebu-devbus driver was compensated by a symetric mistake
in the Armada XP GP Device Tree: a 8 bits bus width was declared, even
though the hardware actually has a 16 bits bus width connection with
the NOR flash.
Now that we have fixed the mvebu-devbus driver to behave according to
its Device Tree binding, this commit fixes the problematic Device Tree
files as well.
This bug was introduced in commit
da8d1b3835 ('ARM: mvebu: Add support for
NOR flash device on Armada XP-GP board') which was merged in v3.10.

AM3517 inherits OMAP3 dts file, but does not have all the IPs
that are present on OMAP3. This patch disables the following
absent IPs for AM3517: Mailbox, IVA, MMU_ISP, MPU_IVA SmartReflex.
A label had to be added for IVA node in omap3.dtsi to be able to
get a reference to the node for disabling.
Otherwise we get the following warnings during booting:
platform iva.2: Cannot lookup hwmod 'iva'
platform 48094000.mailbox: Cannot lookup hwmod 'mailbox'
platform 480bd400.mmu: Cannot lookup hwmod 'mmu_isp'
platform 480c9000.smartreflex: Cannot lookup hwmod 'smartreflex_mpu_iva'

The mailbox module is capable of generating two interrupts
to MPU in OMAP2420, compared to one in OMAP2430. The second
interrupt is to handle interrupts from the additional IVA
processor present only on OMAP2420.
Move the current common mailbox DT node into the SoC
specific files to allow the above differentiation. Also,
added back the interrupt-names on OMAP2420, that were
previously defined in hwmod data.
This fixes regression caused by the recent dropping of
hwmod data in favor for defining it in the .dts files.

Add the mailbox device DT node for OMAP5 SoC. The OMAP5 mailbox
IP is identical to that used in OMAP4.
The OMAP5 hwmod data no longer publishes the module address space,
so this patch fixes the WARN_ON backtrace associated with the
following trace during the kernel boot:
"omap_hwmod: mailbox: doesn't have mpu register target base".
Otherwise we get a warning like this:

Do not reset GPIO5 at boot-up because GPIO5_7 is used
on AM437x GP-EVM to control VTT regulators on DDR3.
Without this some GP-EVM boards will fail to boot because
of DDR3 corruption.

The IGEPv2 board has a SMSC LAN9221i ethernet chip and not a
SMSC LAN911x connected to the GPMC. Each chip needs different
timings in order to operate correctly so is wrong to include
omap-gpmc-smsc911x.dtsi instead of omap-gpmc-smsc9221.dtsi.
