net: dsa: b53: allow VID 0 for BCM5325/65

Now that writing ARL entries works properly, we can actually use VID 0
as the default untagged VLAN for BCM5325 and BCM5365 as well.

So use 0 as default PVID for all chips and do not reject VLAN 0 anymore,
which we ignored since commit 45e9d59d3950 ("net: dsa: b53: do not allow
to configure VLAN 0") anyway.
