Some architectures implement their own memcpy_{to,from}io and memset_io
functions, because the generic memcpy_{to,from}io and memset_io just use
memcpy/memset.This commit replaces the generic memcpy/memset functions
by IO memcpy/memset functions that respect the given architectures
alignment constraints. So, later we can get rid of the individual
implementations and use the generic ones.
