arm64: dts: renesas: r8a77950: Drop operating points above 1.5 GHz
The higher operating frequencies for the Cortex-A57 CPU cores, which
were first documented in the R-Car Gen3 Hardware User's Manual revision
0.54, apply to R-Car H3 ES2.0 (r8a77951).
Play it safe and restrict R-Car H3 ES1.x to 1.5 GHz, by removing the
"turbo-mode" entries from the operating points table inherited from
r8a77951.dtsi.
