Subject: [PATCH v2 1/4] arm64: dts: mt8188: update JPEG encoder/decoder compatible

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".
