This series is the SST-only prerequisite portion of the MSM DP MST
work. It refactors the existing DP code paths so that MST can
plug in cleanly in a follow-up series, without bundling the cleanup
with MST functionality in the same submission.
SST behaviour is preserved end-to-end; no new functionality is added
here. The intent is to land these refactors first to keep the
follow-up MST series focused, smaller, and easier to review.

Changes in v8:
- Rebase to next-20260717.
- Fix comments from sashiko-bot.
- Link to v7: https://lore.kernel.org/r/20260609-dp_mstclean-v7-0-ea04113e8233@oss.qualcomm.com
Changes in v7:
- patch 7: Use WARN_ON_ONCE() when pixel clock is already on. [Konrad]
- Link to v6: https://lore.kernel.org/r/20260602-dp_mstclean-v6-0-2c17ff40a9b2@oss.qualcomm.com
Changes in v6:
- patch 4: fixed the RMW comments. [Dmitry]
- patch 10: do not rename the existing struct. [Dmitry]
- Link to v5: https://lore.kernel.org/r/20260528-dp_mstclean-v5-0-a9221c1f1f3b@oss.qualcomm.com
Changes in v5:
- Split out from v4: only the SST prerequisite cleanup (patches 1-15)
is sent here; the MST implementation will follow on top.
- Rebased onto linux-next-20260527; adapted bridge callbacks to the
new drm_atomic_commit* API.
- patch 3: added Suggested-by: Dmitry Baryshkov.
- patch 4: fixed "splite" typo, reworded body, added RMW comment
covering both SST and MST paths. [Dmitry]
- patch 10: drop cached panel from msm_dp_ctrl_private; pass panel
explicitly to all stream-related dp_ctrl APIs. [Dmitry]
- patch 13/14: introduce bridge wrappers and atomic_prepare with
drm_atomic_commit* from the start to preserve bisectability.
- patch 15: fixed pass panel inside the func. [Dmitry]
- Link to v4: https://lore.kernel.org/all/20260410-msm-dp-mst-v4-0-b20518dea8de@oss.qualcomm.com/
