arm64: dts: imx8mn: Adjust 1.2GHz OPP voltage to OD mode
According to latest datasheet Rev.0, 10/2019, there is restriction
as below:
"If VDD_SOC/GPU/DDR = 0.95V, then VDD_ARM must be >= 0.95V."
As by default SoC is running at OD mode(VDD_SOC = 0.95V), so
VDD_ARM 1.2GHz OPP's voltage should be increased to 0.95V.
