[PATCH 01/19] dt-bindings: arm: mediatek: mmsys: add compatible for MT8196

[Paul Chen]

From: Nancy Lin <nancy.lin@mediatek.com>

In previous SoCs, a single HW pipeline was an independent mmsys,
which included the OVL module, PQ module, and display interface
module.

In the 8196, to increase the flexibility of pipeline connection
and control, the OVL module on a single HW pipeline was separated
into two mmsys, namely ovlsys0 and ovlsys1. The PQ module was also
separated into a dispsys0, and the display interface module was
separated into a dispsys1. Additionally, display power-related
settings are controlled through vdiso-ao.

For example:
The primary path and external path of the display both use
ovlsys0 -> dispsys0 -> dispsys1, forming a pipeline.

The third path of the display uses ovlsys1 -> dispsys0 -> dispsys1,
forming another pipeline.

Therefore, the 8196 needs to add 5 compatible string to support
mmsys for MT8196.
