[PATCH v2 3/9] power: supply: axp20x_usb_power: allow disabling input current limiting

The AXP PMICs allow the user to disable current limiting on the VBUS input. While read-out of this setting was already supported by the driver, it did not allow the user to configure the PMIC to disable current limiting. Add support for this.
