changes v3:
- rework some parts of EEE infrastructure and move it to c45 code.
- add supported_eee storage and start using it in EEE code and by the
  micrel driver.
- add EEE support for ar8035 PHY
- add SmartEEE support to FEC i.MX series.

changes v2:
- use phydev->supported instead of reading MII_BMSR regiaster
- fix @get_eee > @set_eee

With this patch series we provide EEE control for KSZ9477 family of switches and
AR8035 with i.MX6 configuration.
According to my tests, on a system with KSZ8563 switch and 100Mbit idle link,
we consume 0,192W less power per port if EEE is enabled.
