powerpc: add 2 common dcache assembly functions
This patch defines the 2 flush_dcache_range and invalidate_dcache_range
functions for all the powerpc architecture. Their implementation is
borrowed from the kernel's misc_32.S file and replace the ones from
mpc86xx and ppc4xx since they were equivalent.
This is a fix for the problem introduced by this patch:
