usb: dwc3: fix am57xx-idk role-swap during system suspend

Fix the following case for am57xx-idk dual-role port.
-plug host adapter and storage device to dual role port
-suspend system
-remove host adapter
-resume system
-plug via peripheral cable to PC host

The host connector detach is not detected and
DUT doesn't enumerate on PC host.

Calling dwc3_otg_fsm_sync() directly from dwc3_complete() can
lock up the system at xHCI add/remove so we use a work queue for it.
