Freescale introduced new ARM-based socs which using the compatible
clock IP block with PowerPC-based socs'. So this driver can be used
on both platforms.
Updated relevant descriptions and renamed this driver to better
represent its meaning and keep the function of driver untouched.

redefine variable clocks_per_pll as a struct member
If there are multiple PLL clock nodes, this variable will
get overwritten. Redefining it as a struct member can avoid that.

In order to fix the following section mismatch warning:
WARNING: drivers/clk/built-in.o(.data+0xe4): Section mismatch in reference from the variable ppc_corenet_clk_driver to the function .init.text:ppc_corenet_clk_probe()
The variable ppc_corenet_clk_driver references
the function __init ppc_corenet_clk_probe()
If the reference is valid then annotate the
variable with __init* or __refdata (see linux/init.h) or name the variable:
*_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console
WARNING: drivers/clk/built-in.o(.data+0x10c): Section mismatch in reference from the variable ppc_corenet_clk_driver to the variable .init.rodata:ppc_clk_ids
The variable ppc_corenet_clk_driver references
the variable __initconst ppc_clk_ids
If the reference is valid then annotate the
variable with __init* or __refdata (see linux/init.h) or name the variable:
*_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console
We can't just add the __init annotation to ppc_corenet_clk_driver or
remove the __init from ppc_corenet_clk_probe() and ppc_clk_ids.
So choose to use CLK_OF_DECLARE to scan and init the clock devices.

This reverts commit da788acb28.
That commit tried to fix the section mismatch warning by moving the
ppc_corenet_clk_driver struct to init section. This is definitely wrong
because the kernel would free the memories occupied by this struct
after boot while this driver is still registered in the driver core.
The kernel would panic when accessing this driver struct.

The clock bindings for Freescale CoreNet platform are updated.
So, the driver needs to be updated accordingly.
The main changes include:
- Added a new node to present the input system clock
- Changed PLL and MUX's compatible string

Commit b5b4bb3f6a (of: only include prom.h on sparc) removed implicit
includes of of_*.h headers by powerpc's prom.h. Some components were
missed in initial clean-up patch, so add the necessary includes to fix
powerpc builds.

The compatible string of clock is changed from *-2 to *-2.0
on chassis 2. So updated it accordingly.
