Subject: [PATCH] net: dsa: b53: per-port interrupts are optional
Make use of platform_get_irq_byname_optional() to avoid printing
messages on the kernel console that interrupts cannot be found.

Subject: [PATCH] net: dsa: b53: Rename num_arl_entries to num_arl_bins
The variable currently holds the number of ARL bins per ARL buckets,
which is different from the number of ARL entries which would be bins
times buckets. We will be adding a num_arl_buckets in a subsequent patch
so get variables straight now.

Subject: [PATCH] net: dsa: b53: Provide number of ARL buckets
In preparation for doing proper upper bound checking of FDB/MDB entries
being added to the ARL, provide the number of ARL buckets for each
switch chip we support. All chips have 1024 buckets, except 7278 which
has only 256.

Subject: [PATCH] net: dsa: b53: Bound check ARL searches
ARL searches are done by reading two ARL entries at a time, do not cap
the search at 1024 which would only limit us to half of the possible ARL
capacity, but use b53_max_arl_entries() instead which does the right
multiplication between bins and indexes.

new_pvid
Variable new_pvid is being assigned with a value that is never read,
the following if statement updates new_pvid with a new value in both
of the if paths. The assignment is redundant and can be removed.
