[SRU][J:linux-xilinx-zynqmp][PATCH 1/1] arm64: dts: zynqmp: Add ports for the DisplayPort subsystem

[Wei-Lin Chang]

From: Laurent Pinchart <laurent.pinchart at ideasonboard.com>

BugLink: https://bugs.launchpad.net/bugs/2122564

The DPSUB DT bindings now specify ports to model the connections with
the programmable logic and the DisplayPort output. Add them to the
device tree.
