Title: MXC IPU: Replace wait_event with wait_event_interruptible

Having the 4 IPU tasks blocked on wait_event artificially inflates the load average by 4. wait_event_interruptible should be an acceptable alternative.

I applied this patch based on the thread comment http://www.udoo.org/forum/viewtopic.php?f=2&t=149&start=10#p2044

On my quad, the cpu load is much lower and the system feels a lot more responsive now.
