[Intel-gfx] [PATCH v4 0/6] HuC Loading Patches

[Peter Antoine]

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.

    Feedback from D.Gordon and R.Vivi (Thanks).
v3: rebased onto drm-intel-nightly.
    review changed.
v4: rebased on drm-intel-nightly.
    changes for wait_for_atomic.
	error message changes.
	move a function back.
