arm64: dts: renesas: Add missing opp-suspend properties

Browse Source 
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: 800037e815 ("arm64: dts: renesas: r8a774a1: Add operating points")
Fixes: da7e311334 ("arm64: dts: renesas: r8a7796: Add OPPs table for cpu devices")
Fixes: f51746ad7d ("arm64: dts: renesas: Add Renesas R8A77961 SoC support")
