net: dsa: microchip: ksz9477: add Wake on LAN support
Add WoL support for KSZ9477 family of switches. This code was tested on
KSZ8563 chip.
KSZ9477 family of switches supports multiple PHY events:
- wake on Link Up
- wake on Energy Detect.
Since current UAPI can't differentiate between this PHY events, map all
of them to WAKE_PHY.
