arm64: dts: renesas: r8a779f0: Add CA55 operating points
Add operating points for running the Cortex-A55 CPU cores on R-Car S4-8
at various speeds, up to the maximum supported frequency (1200 MHz).
R-Car S4-8 has 8 Cortex-A55 cores, grouped in 4 clusters.
CA55 Sub-System 0 (first 2 clusters / CPU cores 0-3) is clocked by Z0φ.
CA55 Sub-System 1 (last 2 clusters / CPU cores 4-7) is clocked by Z1φ.
As the two sets of clusters are driven by separate clocks, this requires
specifying two separate tables (using the same operating performance
point values), with "opp-shared" to indicate that the CPU cores in each
set share state.
Based on a patch in the BSP by Tho Vu.
