arm64: dts: allwinner: pinephone: Set ALDO3 to exactly 3v0
ALDO3 is used as the power supply for the LRADC keys voltage divider,
in addition to supplying AVCC and VCC-PLL. While AVCC and VCC-PLL will
accept any voltage between 2v7 and 3v3, LRADC needs a precise 3v0 input
to maintain the expected 2:3 ratio between the internal 2v0 reference
voltage and the external supply.
