[Intel-gfx] [PATCH v2 0/4] GuC HWCONFIG with documentation

[Jordan Justen]

This is John/Rodrigo's 2 patches with some minor changes, and I added
2 patches.

"drm/i915/uapi: Add query for hwconfig blob" was changed:

 * Rename DRM_I915_QUERY_HWCONFIG_TABLE to DRM_I915_QUERY_HWCONFIG_BLOB
   as requested by Joonas.

 * Reword commit message

 * I added Acked-by to this patch, but this only applies in the
   context of this version of the patchset. If my changes are
   rejected, then please *do not* add my Acked-by to the other series.

   In particular, I do not want my Acked-by on the patch if the patch
   mentions the HWCONFIG format, but is not willing to add that to the
   actual uAPI.

   I also do not want my Acked-by on it if it mentions "consolidation"
   of this data. Since we are dealing with open source projects (aside
   from GuC), this doesn't seem appropriate.

"drm/i915/uapi: Add struct drm_i915_query_hwconfig_blob_item" adds a
struct to the uAPI and documents the return value for
DRM_I915_QUERY_HWCONFIG_BLOB. (Except, keys / values are still
deferred to the PRM.)

"drm/i915/guc: Verify hwconfig blob matches supported format" does the
simple verification of the blob to make sure it matches what the uAPI
documents.

v2:
 * Fix -Werror errors.
 * Rebase to drm-intel/for-linux-next instead of
   drm-intel/for-linux-next-gt, as this seems to be what CI wants.
 * Fix u32 -> __u32. (Sorry, I was first testing in Mesa tree.)
 * Add commit message for "Verify hwconfig blob" patch as requested by
   Tvrtko.
 * Reword text added to i915_drm.h as requested by Tvrtko. (Attempting
   to indicate the overall blob ends right at the last blob item.)
