arm64: dts: renesas: rzg2l-smarc: Add common dtsi file
RZ/{G2L,V2L} and G2LC SoC use the same carrier board, but the SoM is
different.
Different pin mapping is possible on SoM. For eg:- RZ/G2L SMARC EVK
uses SCIF2, whereas RZ/G2LC uses SCIF1 for the serial interface available
on PMOD1.
This patch adds support for handling the pin mapping differences by moving
definitions common to RZ/G2L and RZ/G2LC to a common dtsi file.
