Well, the affinities need to be the same anyway (so we can tie the
hardware to the description in DT) though we need to use the physical
register to get the MT bit since the binding requires that this be
omitted from the value stored in DT.  Lorenzo was keen on paying
attention to the MT bit which does seem like a reasonable thing to do.
