ftgmac100: implement the new MDIO interface on Aspeed SoC
The PHY behind the MAC of an Aspeed SoC can be controlled using two
different MDC/MDIO interfaces. The same registers PHYCR (MAC60) and
PHYDATA (MAC64) are involved but they have a different layout.
BIT31 of the Feature Register (MAC40) controls which MDC/MDIO
interface is active.
