[PATCH net-next 3/7] net: dsa: b53: use same ARL search result offset for BCM5325/65

[Jonas Gorski <jonas.gorski@gmail.com>]

BCM5365's search result is at the same offset as BCM5325's search
result, and they (mostly) share the same format, so switch BCM5365 to
BCM5325's arl ops.

Fixes: c45655386e53 ("net: dsa: b53: add support for FDB operations on 5325/5365")
