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.
