drm/i915/huc: Add HuC fw loading support
The HuC loading process is similar to GuC. The intel_uc_fw_fetch() is used for both cases. HuC loading needs to be before GuC loading. The WOPCM setting must be done early before loading any of them. v2: rebased on-top of drm-intel-nightly. removed if(HAS_GUC()) before the guc call. (D.Gordon) update huc_version number of format. v3: rebased to drm-intel-nightly, changed the file name format to match the one in the huc package. Changed dev->dev_private to to_i915() v4: moved function back to where it was. change wait_for_atomic to wait_for. v5: rebased. Changed the year in the copyright message to reflect the right year.Correct the comments,remove the unwanted WARN message, replace drm_gem_object_unreference() with i915_gem_object_put().Make the prototypes in intel_huc.h non-extern. v6: rebased. Update the file construction done by HuC. It is similar to GuC.Adopted the approach used in- https://patchwork.freedesktop.org/patch/104355/ <Tvrtko Ursulin> v7: Change dev to dev_priv in macro definition. Corrected comments. v8: rebased on top of drm-tip. Updated functions intel_huc_load(), intel_huc_init() and intel_uc_fw_fetch() to accept dev_priv instead of dev. Moved contents of intel_huc.h to intel_uc.h. v9: change SKL_FW_ to SKL_HUC_FW_. Add intel_ prefix to guc_wopcm_size(). Remove unwanted checks in intel_uc.h. Rename huc_fw in struct intel_huc to simply fw to avoid redundency. v10: rebased. Correct comments. Make intel_huc_fini() accept dev_priv instead of dev like intel_huc_init() and intel_huc_load().Move definition to i915_guc_reg.h from intel_uc.h. Clean DMA_CTRL bits after HuC DMA transfer in huc_ucode_xfer() instead of guc_ucode_xfer(). Add suitable WARNs to give extra info. v11: rebased. Add proper bias for HuC and make sure there are asserts on failure by using guc_ggtt_offset_vma(). Introduce intel_huc.c and remove intel_huc_loader.c since it has functions that do more than just loading.Correct year in copyright. v12: remove invalidates that are not required anymore.
