arm64: dts: renesas: Add Gray Hawk Single board support
Add initial support for the Renesas Gray Hawk Single board, which is based on the R-Car V4M (R8A779H0) SoC: - Memory, - Crystal oscillators, - Serial console. Based on the White Hawk Single DTS, and on a patch for the Gray Hawk board stack in the BSP by Hai Pham.
