Subject: [PATCH v2 net-next v2 01/12] net: dsa: mv88e6xxx: remove basic function flags
All 88E6xxx Marvell switches (even the old not supported yet 88E6060)
have at least an ATU, per-port STP states and VLAN map, to run basic
switch functions such as Spanning Tree and port based VLANs.
Get rid of the related MV88E6XXX_FLAG_{ATU,PORTSTATE,VLANTABLE} flags,
as they are defaults to every chip.
This enables STP on 6185 and removes many inconsistencies on others.
