regulator: Updates for 3.6

Browse source 
A bunch of fixes which are a combination of minor fixes that have been
 shaken down due to greater testing exposure, the biggest block of which
 are for the Palmas driver which hadn't had all the changes required for
 mainline properly tested when it was merged.
