arm64: dts: qcom: add DP Controller to SM8550 DTS

The DP output is shared with the USB3 SuperSpeed lanes and is
usually connected to an USB-C port which Altmode is controlled
by the PMIC Glink infrastructure.

DT changes tying the DP controller to the USB-C port on the QRD
board will be sent later.
