Intel Broxton OpenCL Support Added To Beignet

Intel Broxton hardware now has open-source OpenCL compute support via the Open-Source Technology Center's Beignet project.

Beignet, the free software project exposing GPU compute support for modern Intel graphics hardware on Linux, now supports Broxton SoCs. With this commit authored by Intel's Guo Yejun, forthcoming Atom chips with their Goldmont cores and Gen9 Skylake derived graphics will be able to handle Linux OpenCL acceleration.

Besides the new Beignet code, there are "special versions" of the Linux kernel and libdrm needed for the Broxton support, but Yejun didn't elaborate on the specific versions required.

Currently this will expose OpenCL 1.2 support for Atom Broxton hardware as the OpenCL 2.0 support continues to be developed in a branch of this project.
