Starting with the SM8550 platform, the SSPP & WB Clock Controls are
no more in the MDP TOP registers, but in the SSPP & WB register space.

Add the corresponding SSPP & WB ops and use them before/after calling the
QoS and OT limit setup functions.

Changes in v2:
- moved all force_clk_ctrl code out of vbif
- use major ver test to add force_clk_ctrl op
- do not add clk_ctrl reg into sspp/wb cap struct
- add WB2 on sm8550
- Link to v1: https://lore.kernel.org/r/20231009-topic-sm8550-graphics-sspp-split-clk-v1-0-806c0dee4e43@linaro.org

Neil Armstrong (5):
      drm/msm/dpu: create a dpu_hw_clk_force_ctrl() helper
      drm/msm/dpu: add setup_clk_force_ctrl() op to sspp & wb
      drm/msm/dpu: move setup_force_clk_ctrl handling into plane and wb
      drm/msm/dpu: sm8550: remove unused VIG and DMA clock controls entries
      drm/msm/dpu: enable writeback on SM8550
