[PATCH V6 07/12] arm64: dts: imx8mn-evk: update vdd_soc dvs voltage

From: Peng Fan <peng.fan at nxp.com>

Per schematic, BUCK1 is for VDD_SOC&DRAM&PU_0V9. The nxp,dvs-run-voltage
and nxp,dvs-standby-voltage need set for BUCK1, not BUCK2.
BUCK2 is for A53, which is handled by DVFS, so no need dvs property.
nxp,dvs-run-voltage is not needed, since bootloader must configure
voltage to make system boot well.
