Wesley Cheng a1383b3537 usb: dwc3: gadget: Restart DWC3 gadget when enabling pullup
usb_gadget_deactivate/usb_gadget_activate does not execute the UDC start
operation, which may leave EP0 disabled and event IRQs disabled when
re-activating the function. Move the enabling/disabling of USB EP0 and
device event IRQs to be performed in the pullup routine.

Fixes: ae7e86108b12 ("usb: dwc3: Stop active transfers before halting the controller")
