Many backlights are enabled via GPIO.  We can generalize the GPIO to a
fixed regulator.

The enable regulator needs to be mandatory because there was no good way
to determine the difference between opting out of the regulator, and probe
deferral.

This series of patches is intended to add a dummy regulator (or a GPIO
regulator) for all users of the pwm-backlight.

The last patch in the series will always be the pwm-backlight change to add
this mandatory regulator.  Patches following up to that patch add the
mandatory regulator on a per mach family basis.  Once all users of
pwm-backlight have been patched, this series can be applied in order to
maintain bisectability.
