====================
mlxsw: Introduce TC Flower offload using TCAM

This patchset introduces support for offloading TC cls_flower and actions
to Spectrum TCAM-base policy engine.

The patchset contains patches to allow work with flexible keys and actions
which are used in Spectrum TCAM.

It also contains in-driver infrastructure for offloading TC rules to TCAM HW.
The TCAM management code is simple and limited for now. It is going to be
extended as a follow-up work.

The last patch uses the previously introduced infra to allow to implement
cls_flower offloading. Initially, only limited set of match-keys and only
a drop and forward actions are supported.

As a dependency, this patchset introduces parman - priority array
area manager - as a library.

v1->v2:
- patch11:
  - use __set_bit and __test_and_clear_bit as suggested by DaveM
- patch16:
  - Added documentation to the API functions as suggested by Tom Herbert
- patch17:
