[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.

221 | ---help--- | ||
222 | This enables support for systems with more than one CPU. If you have | ||
223 | a system with only one CPU, say N. If you have a system with more | ||
224 | than one CPU, say Y. Note that the kernel does not currently | ||
225 | support SMP machines with 603/603e/603ev or PPC750 ("G3") processors | ||
226 | since they have inadequate hardware support for multiprocessor | ||
227 | operation. | ||
228 | |||
229 | If you say N here, the kernel will run on single and multiprocessor | ||
230 | machines, but will use only one CPU of a multiprocessor machine. If | ||
231 | you say Y here, the kernel will run on single-processor machines. | ||
232 | On a single-processor machine, the kernel will run faster if you say | ||
233 | N here. | ||
234 | |||
235 | If you don't know what to do here, say N. | ||
