The nWKRQ pin supports an output voltage of either the internal reference
voltage (3.6V) or the reference voltage of
the digital interface 0-6V (VIO).
Add the devicetree option ti,nwkrq-voltage-vio to set it to VIO.

If this property is omitted the reset default, the internal reference
voltage, is used.
