regulator: Updates for v3.19 The main thing this time around is support for suspend mode configuration from DT which will enable some very useful power savings on systems where we can't rely on the bootloader configuration. We still don't really support dynamic configuration of this at runtime, that may come later if there is any demand. - Support for specifying the target regulation mode and voltage during system suspend via DT, enabling power savings in that mode. - Reduce the default verbosity of the logging on boot, improving boot times especially for systems with very large numbers of regulators. - Lots of cleanups and fixes for Maxim PMIC drivers. - New driver for Richtek RT5033.
