mlxsw: reg: Add Policy Engine Multicast Router Binding Table Register

Browse Source 
In Spectrum-2, multicast routing is implemented explicitly using policy
engine (ACL) block. PEMRBT register is used to bind a dedicated ACL group
to a specific IP protocol.
Add the register to be later used in multicast router implementation.
