This looks good but could you please rebase on top of topic/core, it
conflicts with the support for padding bytes.  It's not really entirely
incorrect, the bytes values aren't terribly well defined for register
sizes that aren't integer numbers of bytes as they were never intended
to be used then.  The assumption did leak out into debugfs though.
