[patch net-next/mlxsw internal v2 11/15] mlxsw: reg: Add Policy-Engine General Configuration Register

[Jiri Pirko]

From: Ido Schimmel <idosch at mellanox.com>

The PGCR register configures general Policy-Engine settings.

Specifically, we are going to use it in order to set the default action
base pointer, which determines where the default action (when there is
no hit) is located for each region.
