Compared to previous generation ICs, the MT8189 JPEG decoder requires 34-bit IOVA address space support and only needs a single clock ("jpgdec") instead of two. Therefore, it is added as a standalone compatible string without falling back to older SoCs. Update the binding schema to include the new compatible string and add an `allOf` block with conditional checks. This enforces the single clock requirement for MT8189 while preserving the two-clock requirement ("jpgdec-smi", "jpgdec") for older SoCs.
