From: Karthick Shanmugham <quic_kartshan@xxxxxxxxxxx>
When mhi_irq_handler is a shared interrupt handler. It is the shared
interrupt handlers responsibility to identify its own interrupt and exit
quickly if it is not. If there is no pending event in the event ring
handled, exit the interrupt context returning IRQ_NONE denoting the
interrupt either doesn't belong to this event ring or not handled.
