changes v3:
- use ethernet address of DSA master instead from devicetree
- use dev_ops->wol* instead of list of supported switch
- don't shotdown the switch if WoL is enabled
- rework on top of latest HSR changes

changes v2:
- rebase against latest next

This series of patches provides Wake on LAN support for the KSZ9477
family of switches. It was tested on KSZ8565 Switch with PME pin
attached to an external PMIC.

The patch making WoL configuration persist on system shutdown will be
send separately, since it will potentially need more discussion.
