This commit clears the interrupt reason (INT_REASON) register on the interrupt handler. Without this clearing, the CODA hardware has been observed to get completely stalled on CODA980 variants, requiring a pretty deep hardware reset. The datasheet specifies that the INT_REASON register is set by the CODA hardware, and should be cleared by the host. While the CODA versions that are currently supported by this driver don't seem to need this change, it's a really small change, so it seems a wise thing to do to avoid hitting some rare race-condition in the hardware.
