regulator: Updates for v4.17

A very small set of updates for the regulator API this time around,
 there's a few bug fixes and also:
 
  - Conversion of the regulator API to use GPIO descriptors rather than
    numbers from Linus Walleij.
  - New drivers for Marvell 88PG86x and Qualcomm PM8998 and PMI8998.
