dt-bindings: memory: renesas,rpc-if: Add support for the R9A07G044
SPI Multi I/O Bus Controller on RZ/G2L SoC is almost identical to
the RPC-IF interface found on R-Car Gen3 SoC's.
This patch adds a new compatible string to identify the RZ/G2L family
so that the timing values on RZ/G2L can be adjusted.
