[PATCH v2 1/3] regulator: axp20x: add drivevbus support for axp803

[Jagan Teki]

Like axp221, axp223, axp813 the axp803 is also supporting external
regulator to drive the  OTG VBus through N_VBUSEN PMIC pin.

Add support for it.

thought the same, but this seems to be different regulator from above
AXP_DESC regulators and even binding documentation follow this order.
