arm64: dts: renesas: rzg2lc-smarc: Add macros for DIP-Switch settings

Browse Source 
RZ/G2LC SoM uses DIP-SWitch SW1 for various pin multiplexing functions.

This patch describes DIP-SWitch SW1 settings on SoM and adds the
corresponding macros for enabling pinmux functionality on RZ/G2LC
SMARC EVK.
