In a similar fashion to commit 564c6d727aca ("mlxsw: spectrum_fid: Add
APIs to lookup FID without creating it"), add a corresponding API to
lookup 802.1Q FIDs.This is a prerequisite to VxLAN support with VLAN-aware bridges and will allow us to resolve a 802.1Q FID by its VLAN when an FDB entry is added on the bridge port of the VxLAN device.
