Update MPC5200 drivers to also look for compatible properties in the
form "fsl,mpc5200-*" to better conform to open firmware generic names
recommended practice as published here:

http://www.openfirmware.org/1275/practice/gnames/gnamv14a.html

This patch should *not* break compatibility with older device trees
which do not use the 'fsl,' prefix.  The drivers will still bind against
the older names also.

mpc5200 platform code defines a bunch of map functions which duplicate the
functionality of of_iomap().  Remove them and use of_iomap() instead.

This patch moves a generic pci init code from lite5200
platform file to a common mpc52xx_setup_pci() routine
and adds additional compatibility property verification.

There is no good reason for board platform code to mess with the ROOT_DEV.
Remove it from all in-tree platforms except powermac

This is a follow on to commit 745e1027.
The original patch had this change to lite5200.c, but it got dropped in
the psycho madness that is the 2.6.24 merge window.

The Lite5200 u-boot image doesn't entirely configure the processor
correctly and so Linux needs to fixup the cpu setup in setup_arch.  Fixing
the CPU setup is good, but making it into common code is not a good idea.

New board ports should be encouraged not to take the lead of the lite5200
and instead get their firmware to setup the CPU the right way.

Low-power mode implementation for Lite5200b.
Some I/O registers are also saved here.

A recent U-Boot that supports this (lite5200b_PM_config) is needed.

Remove includes of files that existed in arch/ppc that we dont need in
arch/powerpc anymore.  The following includes were removed:

 <asm/amigappc.h>
 <asm/bootinfo.h>
 <asm/ppcboot.h>
 <asm/ppc_sys.h>
 <asm/residual.h>
 <asm/m8260_pci.h>

This also caused platforms/embedded6xx/mpc7448_hpc2.h to no longer be
needed and thus removed.

Implement deep-sleep on MPC52xx.
SDRAM is put into self-refresh with help of SRAM code
(alternatives would be code in FLASH, I-cache).
Interrupt code must also not be in SDRAM, so put it
in I-cache.
MPC52xx core is static, so contents will remain intact even
with clocks turned off.

Using device_initcall makes it happen for every platform that
compiles this file in. This is really bad, for obvious reasons.

Instead, we use the .init field of the machine description. If
the platform needs the hook to do something specific it can provides
its own function and call mpc52xx_declare_of_platform_devices from
there. If not, the mpc52xx_declare_of_platform_devices function can
directly be used as the init hook.
