Subject: [PATCH] dt-bindings: arm: mediatek: mmsys: change compatible for MT8195

From: "Jason-JH.Lin" <jason-jh.lin@...iatek.com>

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.
