Prashanth K 2333653ef8 usb: dwc3: gadget: Move vbus draw to workqueue context 
[ Upstream commit 54aaa3b387 ]

Currently dwc3_gadget_vbus_draw() can be called from atomic
context, which in turn invokes power-supply-core APIs. And
some these PMIC APIs have operations that may sleep, leading
to kernel panic.

Fix this by moving the vbus_draw into a workqueue context.
