Johan Hovold 9aaa81c336 USB: chipidea: fix interrupt deadlock 
Chipidea core was calling the interrupt handler from non-IRQ context
with interrupts enabled, something which can lead to a deadlock if
there's an actual interrupt trying to take a lock that's already held
(e.g. the controller lock in udc_irq()).

Add a wrapper that can be used to fake interrupts instead of calling the
handler directly.

Fixes: 3ecb3e09b0 ("usb: chipidea: Use extcon framework for VBUS and ID detect")
Fixes: 876d4e1e82 ("usb: chipidea: core: add wakeup support for extcon")
