dt-bindings: power: supply: Add otg regulator binding 



Add a binding for the regulator which controls the OTG chargepath switch.
The OTG switch gets its power from pm8941_5vs1, and that should be
expressed as a usb_otg_in-supply property in the DT node for the
charger driver.  The regulator name is "otg-vbus".

- otg-vbus:

  Usage: optional

  Description: This node defines a regulator used to control the direction

               of VBUS voltage - specifically: whether to supply voltage

               to VBUS for host mode operation of the OTG port, or allow

               input voltage from external VBUS for charging.  In the

               hardware, the supply for this regulator comes from

               usb_otg_in-supply.
