I've noticed that this driver adds a timeout pause of 1 second after
each xfer. This is due to the wait_event_timeout() call in ocores_xfer()
using a "HZ" timeout value and a missing call to wake_up() in
ocores_process() called by the interrupt handler when the state changes
to STATE_DONE at the end of the frame.
This patch adds the missing call resulting in the removal of this 1
second timeout delay after each xfer.
