Guinan Sun June 22, 2020, 6:45 a.m. UTC 
  move read and write xmdio methods
to e1000_phy.* These methods implement PHY clause 45 access
via clause 22 MMD registers (13 and 14). We now need it
for i225 devices access to GPY, but the approach is actually
IEEE-standardized and can be used by various PHY's.
Make these methods common accessible.
