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>

v2:
  - Add SoC name to top-level comment.
