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 dedicated PCS for SGMII mode and one
for USXGMII mode.

(for Rob, I didn't ignore the comments, just want to
make sure the driver side is done, please ignore)
