regulator

This fixes an integration issue with the regulator device tree bindings
which shook out in -rc.  The bindings were overly enthusiatic when
deciding to set a voltage on a regulator and would try to set zero volts
on an unconfigured regulator which isn't supported.

  regulator: Set apply_uV only when min and max voltages are defined
