VREQCTRL - Voltage request control

The VREQCTRL can request additional voltage on the VREGRADIO regulated supply to support +3 dBm TX power on RADIO.

Setting the VREGRADIO.VREQH register will request high voltage. The request is active until the register is cleared. Status register VREGRADIO.VREQHREADY indicates when the regulator has changed to high voltage.
