power_supply: Add driver for the PMU on WM831x PMICs
The WM831x PMICs provide power path management from three sources: a wall supply, USB and a battery with integrated charger. They also provide an additional backup supply with integrated for maintaining always on functionality such as the RTC and monitoring of power switches. After some initial configuration at startup the device operates autonomously, the driver simply provides reporting of the current state.
