This switches the code using a local remapping of the system controller to enable the U300 board to be self-powered over to making the U300-specific syscon compatible with the MFD generic syscon driver, selecting the generic syscon driver, and augmenting the board power code to pick the regmap and manipulate the syscon from the regmap side of things.
