Merge branch 'dsa-rework-EEE-support'

Vivien Didelot says:

====================
net: dsa: rework EEE support

EEE implies configuring the port's PHY and MAC of both ends of the wire.

The current EEE support in DSA mixes PHY and MAC configuration, which is
bad because PHYs must be configured through a proper PHY driver. The DSA
switch operations for EEE are only meant for configuring the port's MAC,
which are integrated in the Ethernet switch device.

This patchset fixes the EEE support in qca8k driver, makes the DSA layer
call phy_init_eee for all drivers, and remove the EEE support from the
mv88e6xxx driver since the Marvell PHY driver should be enough for it.

Changes in v2:
 - make PHY device and DSA EEE ops mandatory for slave EEE operations.
 - simply return 0 in drivers which don't need to do anything to
   configure the port' MAC. Subsequent PHY calls will be enough.
