msm: sde: Correct rotator irq handler to acknowledge irq once
Current handler acknowledges interrupt in both the irq handler
and the irq thread. This clears interrupts that come between the
irq handler and the irq thread. This patch reorganizes irq
acknowledgment to the irq handler and changes the irq thread to
also check for completed requests by comparing request timestamp
and hardware completion timestamp. Upon error or timeout event,
hardware status is dumped to aid irq related fault isolation.
