regulator: Updates for v4.2 Another fairly quiet release, some new drivers with generic handling for minor features but nothing that makes a substantial difference outside of the subsystem or for most boards: - Support for a bunch of new parameters which are present on enough regulators to be worth having generic handling for in the framework. - Fixes for some issues with printing constraints during boot which should probably have gone in for v4.1 but didn't. - New drivers for Dialog DA9062, Maxim MAX77621 and Qualcomm SPMI regulators.
