Merge branch 'net-dsa-b53-ARL-improvements'

Florian Fainelli says:

====================
net: dsa: b53: ARL improvements

This patch series improves the b53 driver ARL search code by
renaming the ARL entries to be reflective of what they are: bins, and
then introduce the number of buckets so we can properly bound check ARL
searches.

The final patch removes an unused argument.
