I just checked the schematics again and actually both VCC and VCCQ are connected to the 3.3V power rail. VCCQ can be connected to the 1.8V PMIC power rail by solder jumper but default is 3.3V. So I think either both should be connected to a fixed 3.3V regulator or removed, since the default system does not support switching these voltages.
