[POWERPC] Split out CPU specific options into a new Kconfig file
A lot of the options in arch/powerpc/Kconfig deal with the CPU menu,
and my next patches add more to them. Moving them to a new
arch/powerpc/platforms/Kconfig.cputype file makes it easier to
follow.
There are no functional changes in here.
