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.

and White Hawk variants"
