[PATCH v4 0/3] Mediatek MT8189 JPEG support

[Jianhua Lin <jianhua.lin@mediatek.com>]

This series is based on tag: next-20260320, linux-next/master

Changes compared with v3:
- The v4 is resending the cover-letter, because the v3 cover-letter was
  not sent successfully.

Changes compared with v2:
- Dropped the dts patch (arm64: dts: mt8188: update JPEG encoder/decoder
  compatible) as it belongs to a different tree/series.
- Patches 1/3 (dt-bindings: decoder):
  - Changed the MT8189 compatible to be a standalone `const` instead of
    an `enum`.
  - Added an `allOf` block with conditional checks to enforce the single
    clock ("jpgdec") requirement for MT8189, while preserving the
    two-clock requirement for older SoCs.
  - Updated commit message to reflect the schema structure changes and
    hardware differences.
- Patches 2/3 (dt-bindings: encoder):
  - Changed the MT8189 compatible to be a standalone `const` instead of
    an `enum` inside the `items` list, as it does not fallback to
    "mediatek,mtk-jpgenc" due to 34-bit IOVA requirements.
  - Updated commit message to explain the standalone compatible design.
- Patches 3/3 (media: mediatek: jpeg):
  - Refined commit message for better clarity regarding 34-bit IOVA and
    single clock configuration.

Changes compared with v1:
- Patches 1/4:
  - Updating commit message
- Patches 2/4, 3/4: 
  - Updating commit message
  - Adjusted property descriptions acorrding to hardware requirements
  - Improved formatting for better readability and consistency
- Patches 4/4:
  - Updating commit message
