sfc: Use CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS where appropriate
For some buffers we use a starting offset of either NET_IP_ALIGN or 0
depending on whether we believe the architecture supports efficient
access to unaligned words. There is now a config macro specifying
whether this is the case, so check that rather than checking for
specific architectures.
