Merge branch 'mlxsw-Spectrum2-acl-prep'

Ido Schimmel says:

====================
mlxsw: Spectrum-2 small ACL preparations

This is the first set of changes towards Spectrum-2 support in the mlxsw
driver. It contains small changes that prepare the code for the later
introduction of Spectrum-2 support.

The Spectrum-2 ASIC uses an algorithmic TCAM (A-TCAM) instead of a
circuit TCAM (C-TCAM) as Spectrum, and thus most of the changes are
around the ACL code.
