[PATCH 5/5] powerpc: Remove unused st_le*() and ld_le* functions

David Gibson

The powerpc specific st_le*() and ld_le*() functions in
arch/powerpc/asm/swab.h no longer have any users. They are also
misleadingly named, since they always byteswap, even on a little-endian
host.

This patch removes them.
