arm64: dts: mt8195: Add edptx and dptx nodes

In MT8195, we use edptx as the internal display interface and use
dptx as the external display interface. Therefore, we need to add
these nodes to support the internal display and the external display.

- Add dp calibration data in the efuse node.
- Add edptx and dptx nodes for MT8195.
