[Intel-gfx] [PATCH 08/10] quick_dump: SWIG chipset interface

[Ben Widawsky]

This isn't strictly necessary it would have been easy enough to simply
convert intel_chipset.h but this should be nice prep work for directly
doing MMIO. It also serves as a nice review point.

It's demonstrated with an autodetect function in the script. That
autodetect has a hardcoded path that shouldn't be there, but it will go
away in the next patch when we can properly link in libpciaccess.

Thanks to Matt for helping whip the automake stuff into shape.
