arm64: dts: renesas: r8a7796[01]: Fix OPP table entry voltages

Correct the voltages in the "Power Optimized" (<= 1.5 GHz) Cortex-A57
operating point table entries for the R-Car M3-W and M3-W+ SoCs from
0.82V to 0.83V, as per the R-Car Gen3 EC Manual Errata for Revision
0.53.

Based on a patch for R-Car M3-W in the BSP by Takeshi Kihara
<takeshi.kihara.df@renesas.com>.

Fixes: da7e3113344fda50 ("arm64: dts: renesas: r8a7796: Add OPPs table for cpu devices")
Fixes: f51746ad7d1ff6b4 ("arm64: dts: renesas: Add Renesas R8A77961 SoC support")
