====================
dpaa2-switch: add mirroring support

This patch set adds per port and per VLAN mirroring in dpaa2-switch.

The first 4 patches are just cosmetic changes. We renamed the
dpaa2_switch_acl_tbl structure into dpaa2_switch_filter_block so that we
can reuse it for filters that do not use the ACL table and reorganized
the addition of trap, redirect and drop filters into a separate
function. All this just to make for a more streamlined addition of the
support for mirroring.

The next 4 patches are actually adding the advertised support. Mirroring
rules can be added in shared blocks, the driver will replicate the same
configuration on all the switch ports part of the same block.

The last patch documents the feature, presents its behavior and
limitations and gives a couple of examples.
