Merge branch 'lynx-pcs-interface-cleanup'

Colin Foster says:

====================
lynx pcs interface cleanup

The current Felix driver (and Seville) rely directly on the lynx_pcs
device. There are other possible PCS interfaces that can be used with
this hardware, so this should be abstracted from felix. The generic
phylink_pcs is used instead.

While going through the code, there were some opportunities to change
some misleading variable names. Those are included in this patch set.
