[PATCH v10 2/3] dt-bindings: media: mediatek-jpeg-encoder: add MT8189 compatible string

Add the compatible string for the JPEG encoder block found in the
MediaTek MT8189 SoC.

Unlike some previous SoCs, the MT8189 JPEG encoder requires 34-bit IOVA
address space support. Therefore, it is added as a standalone compatible
string without falling back to the generic "mediatek,mtk-jpgenc" to
ensure the driver applies the correct hardware-specific configurations.
