Add support for basic power management on
the dwc3 driver. While there is still lots
to improve for full PM support, this minimal
patch will already make sure that we survive
suspend-to-ram and suspend-to-disk without
major issues.

This will be used during resume to verify
if we should reconnect our pullups or not.

we don't need to enable IRQs until we have
a gadget driver loaded and ready to work,
so let's delay IRQ enable to ->udc_start()
and IRQ disable to ->udc_stop().

While at that, also move the related use of
request_irq() and free_irq().

Make the call to dwc3_event_buffers_setup()
and dwc3_event_buffers_cleanup() explicit,
so it's easier to implement PM.
