[PATCH v1 2/2] net: phy: gmii2rgmii: Add support for phy ethernet id configuration

[Tapio Reijonen]

When Kconfig PHY_ETHERNET_ID is set, create external PHY using via
ethernet-phy-id driver to support using starpping resistors
of the external PHY.

Fixes: commit a744a284e354  ("net: phy: Add support for ethernet-phy-id with 
gpio reset")
