regulator: Updates for v4.13 

A quiet release for the regulator API, a series of fairly small fixes
 plus one new feature and a few new drivers:
 
  - Support for regulators with different settling times for rising and
    falling voltage changes.
  - New drivers for Allwinner AXP803, HiSilicon HI6421V530 and TI
    LP87565.
