NET: QE: UEC: Make uec_miiphy_read() and uec_miiphy_write() use the devname arg.
The current uec_miiphy_read and uec_miiphy_write hardcode access devlist[0] This patch makes these function use the devname argument that is passed in to allow access to the phy registers of other devices in devlist[].
