[PATCH 06/18] drm: remove drm_dev_to_irq from drivers

[Daniel Vetter <daniel.vetter@ffwll.ch>]

Only used in some legacy pci drivers, and dereferncing the pci irq is
actually shorter ...

Since this removes all users for drm_dev_to_irq from the tree except
in drm_irq.c, move the inline helper in there. It'll disappear soon,
too.
