net: dsa: mv88e6xxx: factorize MAC address setting

Browse Source 
Some switch models have a dedicated register for Switch MAC/WoF/WoL.
This register, when present, is used to indirectly set the switch MAC
address, instead of a direct write to 3 global registers.

Identify this feature and share a common mv88e6xxx_set_addr function.
