net: dsa: b53: do not allow to configure VLAN 0
Since we cannot set forwarding destinations per VLAN, we should not have
a VLAN 0 configured, as it would allow untagged traffic to work across
ports on VLAN aware bridges regardless if a PVID untagged VLAN exists.
So remove the VLAN 0 on join, an re-add it on leave. But only do so if
we have a VLAN aware bridge, as without it, untagged traffic would
become tagged with VID 0 on a VLAN unaware bridge.
