(Also answering danvet's question on one of my patches).

Those dpio read/write routines are very similar to the SBI ones for LPT,
but some subtle registers changes make them different enough not to be
directly reused AFAIK. So I think we'll have to stick with a set of DPIO
and SBI ops for now.

So other that the other Ben's and Chris'  comments about this:
