drm/i915/irq: move all PCH irq postinstall calls to display code

Browse source 
Unify on making the calls from display code. Need to add an if ladder in
gen8_de_irq_postinstall() for now, but the function looks like it could
be overall be better split by platform. Something for the future.

The display version check for mtp seems a bit suspect, but this matches
current code.
