[net-next,00/19] Multiple cleanup and feature for qca8k

Message

This series contains 3 main patch groups:
- Cleanup with conversion of the driver to bitfield macro and regmap.
- Add multiple feature mdb add/del, lag support, ageing and fast age.
- Code split of common code from specific code.

The first patch is just a reference from linux-next needed for the
regmap conversion.

As said in the commits, the code split is required as ipq40xx internal
switch is based on the same qca8k reg but use a different way to
read/write to the switch regs. We convert the driver to the generic
regmap and we split the driver to common and specific code.

This also contains a patch to fix a corner case when and if multi cpu
will be supported to DSA.
We add mdb add/del using the ARL table.
We add ageing support and fast age.
We add support for mirror mode.
We add 2 additional MIB present on qca8337.

The regmap conversion patch and the lag patch contains checkpatch
warning for too long line and these error are not fixed to not make the
definition of these regs pratically not readable.
