xf86pciBus.c: use Intel ddx only for pre-gen3 hardware

Browse source 
Use intel ddx only on pre-gen4 hw, newer ones will fall back to modesetting.

Instead of defaulting to the Intel driver for all Intel hardware, only
default it for older hardware for which it has shown to be better for.

Note that Debian/Fedora and their derivatives, as well as the yocto project
have been carrying this patch for many years:
192254841a
ee515e44b0

so this simply aligns xserver upstream with Linux distributions.
