Drop most of "extra" features of dpu_hw_blk.
Changes since v2: - Include a patch to fix compilation issue with merge3d id handling
Changes since v1: - Make dpu_hw_blk an empty structure - Split this into separate patchset
---------------------------------------------------------------- Dmitry Baryshkov (4): drm/msm/dpu: remove unused dpu_hw_blk features drm/msm/dpu: drop dpu_hw_blk_destroy function drm/msm/dpu: use struct dpu_hw_merge_3d in dpu_hw_pingpong drm/msm/dpu: hw_blk: make dpu_hw_blk empty opaque structure

Remove all unused dpu_hw_blk features and functions: - dpu_hw_blk_get()/_put() and respective refcounting, - global list of all dpu_hw_blk instances, - dpu_hw_blk_ops and empty implementation inside each hw_blk subdriver.
This leaves dpu_hw_blk as a placeholder with just type and index.

Drop most of "extra" features of dpu_hw_blk.
Changes since v2:
- Include a patch to fix compilation issue with merge3d id handling
Changes since v1:
- Make dpu_hw_blk an empty structure
- Split this into separate patchset
Gracious ping for this patchset.
Dmitry Baryshkov (4): drm/msm/dpu: remove unused dpu_hw_blk features drm/msm/dpu: drop dpu_hw_blk_destroy function drm/msm/dpu: use struct dpu_hw_merge_3d in dpu_hw_pingpong drm/msm/dpu: hw_blk: make dpu_hw_blk empty opaque structure
