MLK-23331 arm64: dts: imx8mn: Update settings according to latest datasheet
According to latest datasheet Rev.0.1, 03/2020, VDD_ARM does
NOT have dependency on VDD_SOC, so below table in datasheet
can be used directly for VDD_ARM:
Clock Voltage
1.2GHz 0.85V
1.4GHz 0.95V
1.5GHz 1.0V
For DDR4 EVK board, system runs at nominal mode, so GPU can
ONLY run up to 400MHz.
For LPDDR4 EVK board, system runs at over-drive mode, so GPU
can run up to 600MHz.
