ARM: dts: AM43XX: Remove min and max voltage values for dcdc3
dcdc3 supplies to DDR on AM43x series. When we set both min and max values to the same value. The regulator framework sets that particular voltage. This is bad as we are changing the ddr voltage when executing from ddr. Hence remove the min and max values. The ddr supply voltage shall be set from bootloader when not executing from ddr and not while executing from kernel.
