Missing Integrated GPU PCI device on Skylake Xeon

FreeBSD does not support OpenCL on Skylake GPUs.
Check the graphics stack wiki:
https://wiki.freebsd.org/Graphics
There is a new driver under development, but afaik even that doesn't
support Skylake yet.
If you want to play around and test the new driver, you can do so. But
we can't promise anything will work.
Driver github:
https://github.com/freebsd/freebsd-base-graphics/tree/drm-i915-update-38
How to test driver:
