Mediatek DRM Next for Linux 5.20

1. Add Mediatek Soc DRM (vdosys0) support for mt8195
2. Cooperate with DSI RX devices to modify dsi funcs and delay mipi high to cooperate with panel sequence
3. Add mt8186 dsi compatible and convert dsi_dtbinding to .yaml
4. Add MediaTek SoC DRM (vdosys1) support for mt8195
5. Add MT8195 dp_intf driver

-Mediatek DSI Device
-===================
-
-The Mediatek DSI function block is a sink of the display subsystem and can
-drive up to 4-lane MIPI DSI output. Two DSIs can be synchronized for dual-
-channel output.
-
-Required properties:
-- compatible: "mediatek,<chip>-dsi"
-- the supported chips are mt2701, mt7623, mt8167, mt8173 and mt8183.
-- reg: Physical base address and length of the controller's registers
-- interrupts: The interrupt signal from the function block.
-- clocks: device clocks
-  See Documentation/devicetree/bindings/clock/clock-bindings.txt for details.
-- clock-names: must contain "engine", "digital", and "hs"
-- phys: phandle link to the MIPI D-PHY controller.
-- phy-names: must contain "dphy"
-- port: Output port node with endpoint definitions as described in
-  Documentation/devicetree/bindings/graph.txt. This port should be connected
-  to the input port of an attached DSI panel or DSI-to-eDP encoder chip.
-
-Optional properties:
-- resets: list of phandle + reset specifier pair, as described in [1].
-
-[1] Documentation/devicetree/bindings/reset/reset.txt
