DisplayPort MST dock support for Fedora 20 copr repo.

So I've created a copr

http://copr.fedoraproject.org/coprs/airlied/mst/

With a kernel + intel driver that should provide support for DisplayPort MST on Intel Haswell hardware. It doesn't do any of the fancy Dell monitor stuff yet, it primarily for people who have Lenovo or Dell docks and laptops that can't currently multihead.

The kernel source is from this branch which backports a chunk of stuff to v3.14 to support this.

It might still have some bugs and crashes, but the basics should in theory work.
