ath25: 4.9: fix Ethernet tiny issues
Few tiny fixes for issues caused by changes in the upstream:
- do not touch PHY IRQ array (core code initializes it itself now)
- add missed SET_NETDEV_DEV() invocation (causes segfault during phy
connection)
- use phy API inside the MDIO probe function instead of direct field
access (consider phy structure changes in upstream and prevent
similar issues in the future)
