regulator: Fixes for v3.16

Browse Source 
A few small fixes:
 
  - Fixes for bugs in Palmas and as3722 exposed by recent changes in the
    core - the drivers weren't allowing the current configuration to be
    read sometimes.
  - Provide a stub for regulator_can_change_voltage() for !REGULATOR.
  - Make sure ltc3589 only looks at its child nodes in the device tree
    rather than searching the whole tree.
