Subject: [PATCH 2/5] dt-bindings: arm: mediatek: mmsys: add mt8195 SoC binding

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

In the SoC before, such as mt8173, it has 2 pipelines binding to one
mmsys with the same clock driver and the same power domain.

In mt8195, there are 4 pipelines binding to 4 different mmsys, such as
vdosys0, vdosys1, vppsys0 and vppsys1.
Each mmsys uses different clock drivers and different power domain.

Since each mmsys has its own mmio base address, they could be identified
by their different address during probe time.
