regulator: Updates for v4.6

Browse source 
This has been an extremely quiet release for the regulator API, aside
 from bugfixes and small enhancements the only thing that really stands
 out are the new drivers for Action Semiconductors ACT8945A, HiSilicon
 HI665x, and the Maxim MAX20024 and MAX77620.
