[PATCH 03/10] phy: rockchip: naneng-combphy: Fix Generic PHY reference counting

Generic PHY reference counting helps ensure driver ops for init/exit and
power on/off are called at correct state. For this to work the PHY
driver must initialize PHY-id to a persistent value in of_xlate ops.

The Rockchip COMBPHY driver does not initialize the PHY-id field, this
typically lead to use of unshared reference counting among different
struct phy instances.

Initialize the PHY-id in of_xlate ops to ensure use of shared reference
counting among all struct phy instances.
