net: dsa: mv88e6xxx: factorize EEE access
Add a MV88E6XXX_FLAG_EEE flag to describe switch models featuring Energy Efficient Ethernet. Use it to conditionally support such access in the common code. Signed-off-by: Vivien Didelot <vivien.didelot@savoirfairelinux.com> Signed-off-by: David S. Miller <davem@davemloft.net>
