Subject: [PATCH 1/2] usb: dwc3: gadget: modify the scale in vbus_draw callback

Currently, vbus_draw callback used wrong scale for power_supply.
The unit of power supply should be uA.
Therefore, this patch will fix this problem.

Fixes: 99288de36020 ("usb: dwc3: add an alternate path in vbus_draw callback")
