[PATCH v1 0/2] drm/atmel-hlcdc: drop use of drm_irq mid-layer

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.

drm_bridge_funcs includes several duplicated operations as atomic
variants has been added over time.
New bridge drivers shall use the atomic variants - mark the deprecated
operations to try to avoid usage in new bridge drivers.

Ignore this patch - I managed to chain the wrong patch to the cover
letter.
