This adds all devices that are normally present through the
u8500_init_machine function in the device tree as well, which
will duplicate the devices that are visible.
This will not do much by itself because the device from the
device tree are not matched by any device driver until they
are converted as well. The next step is to move over one
device at a time to actually be used from the device tree
instead of the hardcoded device using auxdata to pass the
correct platform_data.

This provides very basic Device Tree support for ST-Ericsson's
low-cost development platform, Snowball. If Device Tree for
ux500 is enabled and the correct board is configured within the
Device Tree blob, the correct *_init_machine() will be called.
This patch is based on some original work completed by:

Define both uarts in kirkwood.dtsi as they are common to all kirkwood
SoCs. Each board may enable all or none of them, so they are disabled
by default. uart0 is enabled for the dreamplug.
tclk can vary for each board, so we leave it undefined in the kirkwood
dtsi. Each board can then set it as appropriate when enabling the uart.
