arm64: dts: renesas: r8a779f0: Add secondary CA55 CPU cores

Complete the description of the Cortex-A55 CPU cores and L3 cache
controllers on the Renesas R-Car S4-8 (R8A779F0) SoC, including CPU
topology and PSCI support for enabling CPU cores.

R-Car S4-8 has 8 Cortex-A55 cores, grouped in 4 clusters.

Based on patches in the BSP by Takeshi Kihara.
