====================
net: dsa: mv88e6xxx: augment phylink support for 10G

This series adds phylink 10G support for the 88E6390 series switches,
as suggested by Andrew Lunn.

The first patch cleans up the code to use generic definitions for the
registers in a similar way to what was done with the initial conversion
of 1G serdes support.

The second patch adds the necessary bits 10GBASE mode to the
pcs_get_state() method.
