mlxsw: reg: Add Policy-Engine Region eRP Register
The PERERP register configures the region eRPs. It can be used, for example, to enable lookup in the C-TCAM in addition to the A-TCAM. To be able to perform a lookup in the C-TCAM we need to "use" the eRP table. This is done by marking the pointer as valid, but zeroing the eRP table vector.
