net: phy: xgmiitorgmii: Support generic PHY status read
Some PHY drivers like the generic one do not provide a read_status
callback on their own but rely on genphy_read_status being called
directly.
With the current code, this results in a NULL function pointer call.
Call genphy_read_status instead when there is no specific callback.
