4.6 DRM/i915 update CFT (Sandy Bridge?)/IvyBridge/Haswell/Broadwell/SkyLake/KabyLake supported

[Juan Ramón Molina Menor]

Hi and thanks in advance for your work!

I have a regression with respect to the drm-next-3.9 branch, which works 
well with my Haswell (HD 4400) GPU on a ThinkPad S440: Loading the 
i915kms module through startx or directly with kldload leads to an 
instant panic:

[drm:0xffffffff821aa180s] *ERROR* failed to init modeset
panic: fix mtrrs you schmuck

Unfortunately, I’m booting this laptop with a small USB stick just for 
testing and cannot get cores, but I’ve uploaded a crappy image of the 
crash to the wiki page of the laptop, where supplementary information is 
available:

Let me know if I can help somehow.

Best regards,
Juan
