arm64: dts: renesas: Add missing opp-suspend properties
[ Upstream commit 44b615ac9fab16d1552cd8360454077d411e3c35 ]
Tag the highest "Power Optimized" (1.5 GHz) Cortex-A57 operating point
table entries for the RZ/G2M, R-Car M3-W and M3-W+ SoCs with the
"opp-suspend" property. This makes sure the system will enter suspend
in the same performance state as it will be resumed by the firmware
later, avoiding state inconsistencies after resume.
Based on a patch for R-Car M3-W in the BSP by Takeshi Kihara
<takeshi.kihara.df@renesas.com>.
Fixes: 800037e815b91d8c ("arm64: dts: renesas: r8a774a1: Add operating points")
Fixes: da7e3113344fda50 ("arm64: dts: renesas: r8a7796: Add OPPs table for cpu devices")
Fixes: f51746ad7d1ff6b4 ("arm64: dts: renesas: Add Renesas R8A77961 SoC support")
