[PATCH 1/2] arm64: dts: qcom: sc8280xp-x13s: Enable HBR3 on external DPs

[Jens Glathe via B4 Relay]

From: Jens Glathe <jens.glathe@xxxxxxxxxxxxxxxxxxxxxx>

When no link frequencies are set, the msm/dp driver defaults to HBR2.
Explicitly list the supported rates including HBR3 (8.1 Gbps) on both
USB-C DisplayPort endpoints so high-resolution docks and monitors can
train above 5.4 Gbps.
