[ Upstream commit fd7d474841 ]
When the OTG port is fixed to host mode, the driver does not request its
IRQs, nor does it enable those IRQs in hardware. Similarly, the driver
should ignore the OTG port IRQs when handling the shared interrupt.
Otherwise, it would update the extcon based on an ID pin which may be in
an undefined state, or try to queue a uninitialized work item.
