drm/i915: Nuke drm_driver irq vfuncs
Stop using the irq vfuncs under drm_driver. That's not going to fly
in a mixed gen environment since the structure is shared between all
the devices.
v2: Allow intel_irq_uninstall() to be called twice due to
intel_modeset_cleanup() calling it as well. Toss in a
FIXME to remind us that this is not great.
