regulator: Fixes for v6.10

Browse source 
A bunch of fixes that came in during the merge window, Matti found
 several issues with some of the more complexly configured Rohm
 regulators and the helpers they use and there were some errors in the
 specification of tps6594 when regulators are grouped together.
