Subject: [PATCH 5.19 0235/1157] arm64: dts: renesas: r8a779m8: Drop operating points above 1.5 GHz

From: Geert Uytterhoeven <geert+renesas@...der.be>

[ Upstream commit f48cb21a28c07d0754d5f2f85444cfb0e7b1fd05 ]

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.
