Enable RMII interface in the lan743x driver for PHY and MAC
configuration.

- Select RMII interface in lan743x_phy_interface_select().
- Update phylink supported_interfaces and MAC capabilities.
- Enable RMII via RMII_CTL in lan743x_hardware_init().
- Define RMII_CTL register and enable bit in lan743x_main.h.

So EEE is not supporting with RMII? This is not mentioned in the commit
message.

Humm, is this an 802.3 limitation, or a limitation of this hardware?
If this is 802.3, then this should be in phylink, not drivers.

[Thangaraj Samynathan] No. This is the limitation of hardware. Will update
The commit message in next revision.
