usb: dwc2: Fix UDC state tracking

It has been noticed that the dwc2 udc state reporting doesn't
seem to work (at least on HiKey boards). Where after the initial
setup, the sysfs /sys/class/udc/f72c0000.usb/state file would
report "configured" no matter the state of the OTG port.

This patch adds a call so that we report to the UDC layer when
the gadget device is disconnected.

This patch does depend on the previous patch ("usb: dwc2:
Improve gadget state disconnection handling") in this patch set
in order to properly work.
