mlxsw: reg: Add fields to RITR - Router Interface Table Register

Browse Source 
Add fields relevant for Spectrum-2 Loopback IPinIP router interface
creation. Add additional Loopback RIF protocol value - Generic, used for
creation of an explicit underlay RIF, and also add a field named
underlay_rif used for specifying the underlay RIF of a tunnel.
