Partially revert "powerpc: Remove duplicate cacheable_memcpy/memzero functions"
This partially reverts
commit 'powerpc: Remove duplicate cacheable_memcpy/memzero functions
("b05ae4ee602b7dc90771408ccf0972e1b3801a35")'
Functions cacheable_memcpy/memzero are more efficient than
memcpy/memset as they use the dcbz instruction which avoids refill
of the cacheline with the data that we will overwrite.
