arm64: dts: imx8mm-kontron: Make sure SOC and DRAM supply voltages are correct

Browse source

It looks like the voltages for the SOC and DRAM supply weren't properly
validated before. The datasheet and uboot-imx code tells us that VDD_SOC
should be 800 mV in suspend and 850 mV in run mode. VDD_DRAM should be
950 mV for DDR clock frequencies of up to 1.5 GHz.

Let's fix these values to make sure the voltages are within the required
range.
