Drop the limitation of a single PCS in pcs-handle property. Multiple PCS
can be defined for an ethrnet-controller node to support various PHY
interface mode type.

It's very common for SoCs to have a 2 or more dedicated PCS for Base-X
(for example SGMII, 1000base-x, 2500base-x, ...) and Base-R (for example
USXGMII,10base-r, ...) with the MAC selecting one of the other based on
the attached PHY.
