power: Add an axp20x-usb-power driver
This adds a driver for the usb power_supply bits of the axp20x PMICs. I initially started writing my own driver, before coming aware of Bruno Prémont's excellent earlier RFC with a driver for this. My driver was lacking CURRENT_MAX and VOLTAGE_MIN support Bruno's drvier has, so I've copied the code for those from his driver. Note that the AC-power-supply and battery charger bits will need separate drivers. Each one needs its own devictree child-node so that other devicetree nodes can reference the right power-supply, and thus each one will get its own mfd-cell / platform_device and platform-driver.
