drm/i915: Use chipset-specific irq installers
drm/i915: Use chipset-specific irq installers

Konstantin Belousov pointed out that 4697995b98417 replaced the generic
i915_driver_irq_*install() functions with chipset specific routines
accessible only through driver->irq_*install(). So update the sanity
check in i915_request_wait() to match.
