[PATCH 2/2] arm64: dts: qcom: sm8250: add a link between DWC3 and QMP PHY

[Dmitry Baryshkov <dmitry.baryshkov@linaro.org>]

The SuperSpeed signals originate from the DWC3 host controller and then
are routed through the Combo QMP PHY, where they are multiplexed with
the DisplayPort signals. Add corresponding OF graph link.
