Subject: [PATCH v6 0/7] media: qcom: iris: add support for SM8650

Add support for the IRIS accelerator for the SM8650
platform, which uses the iris33 hardware.

Sm sm8650 SoC support also reorganizes slighly by renaming
the sm8550 plaform file to gen2, and move soc specific data
into headers.

The vpu33 requires a different reset & poweroff sequence
in order to properly get out of runtime suspend.

Based on the downstream implementation at:
- https://git.codelinaro.org/clo/la/platform/vendor/opensource/video-driver/
  branch video-kernel.lnx.4.0.r4-rel

Changes in v6:
- Removed catalog files, renamed sm8550 soc file to gen2 platform file
- Moved SoC specific into soc specific headers when adding sm8650
- Rebased on next, fixed bindings
- Fixed errors reported by CI
- Link to v5: https://lore.kernel.org/all/20250410-topic-sm8x50-upstream-iris-catalog-v5-0-44a431574c25@linaro.org

Changes in v5:
- Reorganized into catalog, rebased sm8650 support on top
- Link to v4: https://lore.kernel.org/r/20250409-topic-sm8x50-iris-v10-v4-0-40e411594285@linaro.org

Changes in v4:
- collected tags
- un-split power_off in vpu3x
- removed useless function defines
- added back vpu3x disappeared rename commit
- Link to v3: https://lore.kernel.org/r/20250407-topic-sm8x50-iris-v10-v3-0-63569f6d04aa@linaro.org

Changes in v3:
- Collected review tags
- Removed bulky reset_controller ops

- Link to v2: https://lore.kernel.org/r/20250305-topic-sm8x50-iris-v10-v2-0-bd65a3fc099e@linaro.org

Changes in v2:
- Collected bindings review
- Reworked rest handling by adding a secondary optional table to be used by controller poweroff
- Reworked power_off_controller to be reused and extended by vpu33 support
- Removed useless and unneeded vpu33 init
- Moved vpu33 into vpu3x files to reuse code from vpu3
- Moved sm8650 data table into sm8550
- Link to v1: https://lore.kernel.org/r/20250225-topic-sm8x50-iris-v10-v1-0-128ef05d9665@linaro.org
