====================
net: dsa: b53: add support for BCM5389/97/98 and BCM63XX ARL formats

Currently b53 assumes that all switches apart from BCM5325/5365 use the
same ARL formats, but there are actually multiple formats in use.

Older switches use a format apparently introduced with BCM5387/BCM5389,
while newer chips use a format apparently introduced with BCM5395.

Note that these numbers are not linear, BCM5397/BCM5398 use the older
format.

In addition to that the switches integrated into BCM63XX SoCs use their
own format. While accessing these normal read/write ARL entries are the
same format as BCM5389 one, the search format is different.

So in order to support all these different format, split all code
accessing these entries into chip-family specific functions, and collect
them in appropriate arl ops structs to keep the code cleaner.

Sent as net-next since the ARL accesses have never worked before, and
the extensive refactoring might be too much to warrant a fix.
