[POWERPC] spufs: use memcpy_fromio() to copy from local store
[POWERPC] spufs: use memcpy_fromio() to copy from local store

GCC may generates inline copy loop to handle memcpy() function
instead of kernel defined memcpy(). But this inlined version of memcpy()
causes an alignment interrupt when copying from local store.

This patch uses memcpy_fromio() and memcpy_toio to copy local store
to prevent memcpy() being inlined.
