usb: chipidea: use seperate role sm when using extcon
Enable the code from commit 'aa5fc842bb05 usb: chipidea: use of extcon
framework to work for non OTG case' if ID and/or VBUS signals are taken
from extcon.
Otherwise (observed on a Colibri iMX6ULL) when booting in the ROLE_HOST
and then changing to ROLE_GADGET the gadget does not appear on the bus
and switching back to ROLE_HOST does also no longer detect any connected
USB devices.
