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. Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> --- An alternative naming candidate would be "r8a779h0-gray-hawk-s.dts". As the Gray Hawk and White Hawk board stacks share all boards except for the CPU board, we might be able to reuse white-hawk-common.dtsi[1] once all needed SoC support has been added to r8a779h0.dtsi.
