Sean Anderson f4c2b1eb1f pmd_dp83223: Don't intentionally cause bit errors 
On stretches without transitions, we can lose (or gain) a bit, depending
on how the reciever is reckoning. This can cause spurious test failures
when we get especially unlucky. Keep track of our running disparity
(time-wise, not value-wise) and keep perfect time until we get a
transition (or we start moving back in the right direction).

Sean Anderson cf0aed4980 pmd_io: Rename to pmd_dp83223_rx 
This better reflects that this is an interface intended to be used with
the DP83223. While we're at it, refactor the module to just handle the
the recieve portion.
