Renesas  RZ/G SoC also have the SCIF, SCIFA, SCIFB, and HSCIF ports.
Document RZ/G1[ME] (also known as R8A774[35]) SoC bindings along with
the RZ/G family bindings.  The driver itself also needs to recognize
the latter binding for the SCIF ports, so teach it...

However, I wouldn't bother adding RZ/G family-specific DT bindings, as
RZ/G is a derivative of R-Car Gen2.

    Then we shouldn't have added gen2/3 bindings too since they resolve to the 
same register mapping as gen1. :-)
