This patch series enables the HuC loading. These patches are a port of the
patches that were created by Yu Dai (Alex) and have been ported to work with
the new GuC patches.
The series include a patch to enable the HuC on BXT. This is a separate patch
as the state of the BXT HuC firmware is still in flux, so the patch can be
dropped without delaying the series.
v2: rebased onto drm-intel-nightly.
Also, patch 1 has been recreated as the upstream version of the function
had change significantly making the old patch obsolete.
Also, due to a code move i915_dma.c -> i915_drv.c some code was being
applied to a deleted file.
Also HuC file versions and formats changed.
v3: rebased onto drm-intel-nightly.
review changed.
v4: rebased on drm-intel-nightly.
