[Impact]
* Fixes crash when using SNA with fglrx IGPU mode.
* Adds UXA support for broadwell.

[Test Case]
* On an affected system:
* Run aticonfig --px-igpu to force intel driver being used.
* Disable gpu-manager, set accelmethod in /etc/X11/xorg.conf to UXA or SNA
* SNA: Observe a crash in freescreen, while a normal xserver with full acceleration is expected.
* UXA (default): xserver starts normally, but llvmpipe is used and no acceleration is used in intel at all.

[Regression Potential]
* Adding pci-id and names for broadwell and crv should always be safe, no regressions expected there.
* The uxa patches seem to be a noop for < gen8, which means I don't expect any regressions either.
* The sna-freescreen patch can not make things worse, because if sna is NULL the next statement would already crash, so in the worst case intel would crash elsewhere.
* I'll watch for regressions in -proposed, but I don't expect any from them because those patches are in utopic too. :-)
