Changes in v2:
 - Revised comments for usb_ep_disable() as it should be safe to be
   executed in atomic contexts as well.  Other FDs are currently
   calling ep disable during the disconnect event as well.

This series calls the usb_ep_disable() API directly from fsg_disable()
as there is a possibility that UDCs that support runtime PM may
already be in a suspended state, leading to HW access while resources
are disabled.
