net: dsa: hellcreek: Report VLAN table occupancy
The VLAN membership configuration is cached in software already. So, it can be
reported via devlink. Add support for it:
|root@tsn:~# devlink resource show platform/ff240000.switch
|platform/ff240000.switch:
| name VLAN size 4096 occ 4 unit entry dpipe_tables none
