powerpc: Remove duplicate cacheable_memcpy/memzero functions
These functions are only used from one place each. If the cacheable_*
versions really are more efficient, then those changes should be
migrated into the common code instead.
NOTE: The old routines are just flat buggy on kernels that support
hardware with different cacheline sizes.
