drm/i915/irq: abstract i9xx_display_irq_enable_mask()

Browse Source 
Figure out the enable mask for display things in display code. Reuse the
same function for both i915 and i965 code, the end result remains the
same.

This removes a pair of DISPLAY_VER() and HAS_HOTPLUG() checks from core
irq code.
