regmap: Updates for v3.7

Browse source 
A quiet release for the regmap core, essentially all the activity is in
 the shared interrupt controller which is being more and more widely
 used and has been enhanced to support a wider range of masking types and
 wake handling methods, plus integration with runtime PM for devices
 making aggressive use of that.
