net: dsa: b53: fix BCM5325/65 ARL entry VIDs
BCM5325/65's ARL entry registers do not contain the VID, only the search
result register does. ARL entries have a separate VID entry register for
the index into the VLAN table.
So make ARL entry accessors use the VID entry registers instead, and
move the VLAN ID field definition to the search register definition.
Fixes: c45655386e53 ("net: dsa: b53: add support for FDB operations on 5325/5365")
