For previous MediaTek SoCs, such as MT8173, there are 2 display HW
pipelines binding to 1 mmsys with the same power domain, the same
clock driver and the same mediatek-drm driver.
For MT8195, VDOSYS0 and VDOSYS1 are 2 display HW pipelines binding to
2 different power domains, different clock drivers and different
mediatek-drm drivers.
Therefore, we need to separate these two different mmsys hardwares to
2 different compatibles for MT8195.

If I understand correctly support for vdosys0 is merged with the old compatible.
We should therefore keep mediatek,mt8195-mmsys as a fallback for
mediatek,mt8195-vdosys0.
