I created ppc_md was to allow for different machines to run off a single
binary but not different chip families.
A big #ifdef for the chip-type would work fine since the chip family is
known at compile time. The machine type isn't always know which is the
reason for ppc_md.
I thought one of the linuxppc desgin goals was to keep the ifdefs to a
minimum. I can see idle.c growing quite large and full of #ifdefs if we
do it that way. Rather than using ppc_md, make power_save an
abstraction similar to platform_init.
