The JPEG encoder and decoder of MT8188 share the same architecture and features as those of MT8189, both use a 34-bit iova address-space (16GB) and a single clock configuration. Previously, MT8188 was incorrectly defined alongside SoCs with 32-bit iova address-space (4GB), such as "mediatek,mt2701-jpgdec" and "mediatek,mtk-jpgenc". This mismatch results in an ABI break, as MT8188 cannot function correctly under the 32-bit iova address-space (4GB) configuration. Therefore, MT8188 needs to inherit from MT8189. Update "mediatek,mtk-jpgenc" to "mediatek,mt8189-jpgenc", update "mediatek,mt2701-jpgdec" to "mediatek,mt8189-jpgdec".
