Subject: [PATCH net-next v2 3/7] net: dsa: mv88e6xxx: add switch info
Add a new switch info structure which will be later extended to store
switch models static information, such as product number, name, number
of ports, number of databases, etc.
Merge the lookup function in the probing code, so that we avoid multiple
checking of the MII bus, as well a multiple ID reading.
