Intel TGP dekstop cannot detect second monitor.

Remove an IRQ setup routine and re-order some other IRQ setups.

1. Boot up the system with single monitor connected.
2. Hotplug second monitor.
With the fix applied, the system can detect the 2nd monitor correctly.

[Where problems could occur]
This fix removed some special handling for early gen Core, so HPD on
those old Core systems might be affected.
