mmc: mtk-sd: add support for MT8189 SoC

Browse Source 
Even though MMC IP in MT8189 SoC is partially compatible with the one
found in MT8196 SoC, its register layout has some slight differences
and additional features such as the system power management release
resource control support.
Thus, add new compatible and platform data to support this SoC.
