[v4,4/4] arm64: dts: mediatek: cherry: Add edptx and dptx support
Commit Message
In cherry projects, we use edptx as the internal display interface
and use dptx as the external display interface. To support this, we
need to add more properties.
- Add pinctrls for edptx and dptx.
- Add ports for edptx and dptx.
The port connections for the internal and external display:
dp-intf0 -> edptx -> panel
dp-intf1 -> dptx
The edptx endpoint is kept empty for now, as the panel addition will
come in a later commit.
