[Ignore the first mail - wrong patch was attached]
Two small patches to drop the use of the drm irq mid-layer.
My atmel hlcdc target has stopped working - so unfortunately un-tested :-(
I picked up this to continue the work of Thomas Zimmermann.

This is in preparation for removal of drm_irq use.
Functions are moved without any other changes.

The drm mid-layer for irq's is not relevant for atomic display drivers,
and will be available only for legacy drivers in the future.
Drop usage in the atmel hlcdc driver.

I tested this patch set on the 9x60ek board and unfortunately it causes
errors. The vbltest returns -1 and I also see the display get out of
sync while testing with a gui application.

Thanks a lot for the testing, I will take a look tomorrow and see if I
can figure out what is wrong.
