MLK-25465-2: arm64: dts: imx8mn-ddr4-evk: update vdd_soc in suspend to 0.75v

To match with the latest datasheet, besides, correct vdd_soc to buck1
instead of buck2. But this patch should be no any impact since uboot
has already done the same thing. Anyway correct it, since rohm driver
has this ability now and could be indepedent of  uboot in the future.
