[PATCH v2 00/14] Add MediaTek SoC DRM (vdosys1) support for mt8195

[Nancy.Lin]

The hardware path of vdosys1 with DPTx output need to go through by several modules, such as, PSEUDO_OVL and MERGE.

Add DRM and these modules support by the patches below:

Change in v2:
- Merge PSEUDO_OVL and ETHDR into one DRM component.
- Add mmsys config API for vdosys1 hardware setting.
- Add mmsys reset control using linux reset framework.
