net: dsa: mv88e6xxx: rework Switch MAC setter

Browse source

Switches such as 88E6185 as 3 Switch MAC registers in Global 1. Newer
chips such as 88E6352 have freed these registers in favor of an indirect
access in a Switch MAC/WoL/WoF register in Global 2.

Explicit this difference with G1 and G2 helpers and flags.

Also, note that this indirect access is a single-register which doesn't
require to wait for the operation to complete (like Switch MAC, Trunk
Mapping, etc.), in contrary to multi-registers indirect accesses with
several operations and a busy bit.
