This is deliberate behaviour, apply_uV can only be used with a fixed
voltage at startup in order to avoid issues with handover from the
bootloader if we suddenly drop the supply voltage on a device which has
not yet been claimed by a driver. The expectation is that if the
voltage can vary then something that understands the hardware state
needs to be involved in maintaining the voltage.
