video: da8xx: Register IRQ as last thing in driver probing.
Following commit exposed a bug in driver:
"fbdev: da8xx/omap-l1xx: implement double buffering"
Bug is, if interrupt handler is called before initialization is
finished, raster controller is enabled and following register
modifications causes hardware to stay in a broken state.
By looking at this one may say that proper locking is missing in
this driver, and a more proper fix should be prepared. However,
aformentioned commit causes a regression in the driver and some
fix to current one should be applied first.
