drm/i915/irq: add platform specific display irq ack functions

Add i9xx_display_irq_ack() and vlv_display_irq_ack() to group together
the various irq ack parts for the platforms, to declutter the core i915
irq code from the details.

Introduce struct intel_display_irq_state to group together all the data
the ack functions need. In the follow-up, this state will be passed on
to similar platform specific handler functions.
