dt-bindings: mfd: Add documentation for S2MU005 PMIC
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.
