The vdd3p0 LDO's input should be from external USB VBUS directly, NOT PMIC's power supply, the vdd3p0 LDO's target output voltage can be controlled by SW, and it requires input voltage to be high enough, with incorrect power supply assigned, if the power supply's voltage is lower than the LDO target output voltage, it will return fail and skip the LDO voltage adjustment, so remove the power supply assignment for vdd3p0 to avoid such scenario.
