From: Hai Pham <hai.pham.ud@renesas.com>

Add initial support for the Renesas R-Car V4M (R8A779H0) SoC.

Signed-off-by: Hai Pham <hai.pham.ud@renesas.com>
Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be>

v2:
  - Add vendor-prefixes to DT binding definition header files.

Changes compared to the BSP:
  - Add "-clk" suffix to clock node names,
  - Rename "pmu_a76" node to "pmu-a76",
  - Drop bogus CPU masks from GICv3 PPI interrupt specifiers,
  - Drop hscif0 dmas and dma-names placeholder,
  - Add missing hypervisor virtual timer IRQ to timer node.
