Samsung's S2MU005 PMIC includes subdevices for a charger, an MUIC (Micro USB Interface Controller), and flash and RGB LED controllers. Add the compatible and documentation for the S2MU005 PMIC. Also, add an example for nodes for supported sub-devices, i.e. MUIC, flash LEDs, and RGB LEDs. Charger sub-device uses the node of the parent.
