Drop the own PHY polling function and switch to using the kernel PHY
state machine. This change allows driver to work correctly with devices
that do not support PHY behaviour but whose driver could emulate
autonegotiation completion (e.g. MV88E6060 and IP17xx switches).
NB: earlier this driver rely on flaws in PHY core code and could use PHY
device without really starting it. But now (at least in kernel 4.9)
this trick no more work and network interface could stuck in not-running
state.

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)
