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.
