regulator: Fixes for v4.7

Browse source 
Some driver specific fixes for the regulator subsystem:
 
  - Some of the changes to the core that were merged in the last merge
    window exposed the fact that the qcom-smd driver hadn't implemented
    the voltage enumeration interfaces like it should.  Since it's a
    simple driver specific fix to implement them do that.
  - Fix the ramp delay configuration for tps51632.
