[PATCH 2/5] arm64: dts: renesas: r8a779g0: Add secondary CA76 CPU cores

[Geert Uytterhoeven]

Complete the description of the Cortex-A76 CPU cores and L3 cache
controllers on the Renesas R-Car V4H (R8A779G0) SoC, including CPU
topology and PSCI support for enabling CPU cores.

R-Car V4H has 4 Cortex-A76 cores, grouped in 2 clusters.

Based on a patch in the BSP by Takeshi Kihara.

Signed-off-by: Geert Uytterhoeven <geert+renesas at glider.be>
---
Changes compared to the BSP:
  - Move device_type and enable-method properties,
  - Fix PSCI compatible value for PSCI v1.0,
  - Drop "arm,armv8" compatible values.
