Following on from the discussion we had here and a bit off offline
discussion with Stephen it seems that we need to drop this since having
it in the DT as a separate regulator doesn't really represent the
hardware.  The SAW is controlling the underlying PMIC regulator and we
will eventually need to control that regulator directly so the SAW
should be presented as an alternative control interface for the PMIC
regulator.
