arm64: dts: mediatek: mt8188: Add eDP and DP TX nodes

Add edp-tx and dp-tx nodes for the Embedded DisplayPort (eDP) and
DisplayPort ports to connect to DP-INTF ports and panels, and add the
efuse cell for the DP calibration data.

Individual board device tree should enable the nodes and connect input
and output ports as needed.
