[arswitch] begin tidying up the learning and ATU management, introduce ATU APIs.

* Refactor the initial learning configuration (port learning, address expiry,
  handling address moving between ports, etc, etc) into a separate HAL routine
* and ensure that it's consistent between switch chips - the AR8216,8316,724x,9331
  SoCs all share the same switch code.
* .. the AR8327 needs doing - the defaults seem OK for now
* .. the AR9340 is different but it's also programmed now.

* Add support for flushing a single port worth of ATU entries
* Add support for fetching the ATU table from AR8216 and derived chips

Tested:

* AR9344, Carambola 2

TODO:

* Further testing on other chips
* Add AR9340 support
* Add AR8327 support
