net: dsa: b53: fix ARL accesses for BCM5325/65 and allow VID 0

ARL entries on BCM5325 and BCM5365 were broken significantly in two
ways:

- Entries for the CPU port were using the wrong port id, pointing to a
  non existing port.
- Setting the VLAN ID for entries was not done, adding them all to VLAN
  0 instead.

While the former technically broke any communication to the CPU port,
with the latter they were added to the currently unused VID 0, so they
never became effective. Presumably the default PVID was set to 1 because
of these issues 0 was broken (and the root cause not found).

So fix writing and reading entries on BCM5325/65 by first fixing the CPU
port entries, then fixing setting the VLAN ID for entries.

Finally, re-allow VID 0 for BCM5325/65 to allow the whole 1-15 VLAN ID
range to be available to users, and align VLAN handling with all other
switch chips.
