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.

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.

Adds utility routines used by 52xx device drivers and board support
code.  Main functionality is to add device nodes to the of_platform_bus,
retrieve the IPB bus frequency, and find+ioremap device registers.
