The highest-performance mode for the Cortex-A57 CPU cores supported on
R-Car H3Ne (R8A779M8) is the Power Optimized (1.5 GHz) mode. The Normal
(1.6 GHz) and High Performance (1.7 GHz) modes are not supported.
Hence drop the "turbo-mode" entries from the operating points table
inherited from r8a77951.dtsi.
Fixes: 6e87525d751fac57 ("arm64: dts: renesas: Add Renesas R8A779M8 SoC support")

The same is true for R-Car H3-N, but we do not have a separate .dtsi
for R-Car H3-N yet, as it uses the same part number (R8A77951) and
compatible values (r8a7795-based) as R-Car H3.
To be queued in renesas-devel for v5.20.
