mlxsw: reg: Prepare PERERP register for A-TCAM usage
Before introducing A-TCAM support we need to make sure all the necessary
fields are configurable and not hard coded to values that worked for the
C-TCAM only use case.
This includes - for example - the ability to configure the eRP table
used by the TCAM region.
