MLK-17459-1: drm: imx: dcss: change ctxld irq handling

To remove any possible latencies introduced by scheduling the bottom
half interrupt handler, do everything in the top half handler and get
rid of the IRQ worker thread handler. Also, that needs all mutexes
changed to spinlocks since mutexes can sleep.
