drm/mediatek: Change mmsys compatible for mt8195 mediatek-drm

Browse Source 
Because compatible of mt8195 is changing from "mediatek,mt8195-mmsys"
to "mediatek,mt8195-vdosys0".

We have to revert the multiple compatible finding function and
add driver data of mt8195 vdosys0 to mediatek-drm and the sub driver.
