Adhemerval Zanella b269211467 powerpc: wordcopy/memmove cleanup for ppc64
This patch cleanup some multiarch code related to memmmove
optimization. Initial IFUNC support added specialized wordcopy
symbols which turned in local IFUNC calls used by memmove default
implementation.

This change by removing then and used the optimized memmove instead
for supported chips.
