[PATCH v2 2/2] arm64: dts: qcom: sc8280xp-microsoft-blackrock: Enable 4-lane DP altmode

[Jens Glathe via B4 Relay]

From: Jens Glathe <jens.glathe@xxxxxxxxxxxxxxxxxxxxxx>

Allow up to 4 lanes for the DisplayPort links on the USB-C ports and
the mini-DP connector. Add the standard link-frequencies and move
data-lanes to the out endpoints where required by the current bindings.

Also enable mode-switch on the QMP combo PHYs so that altmode events
can reach them.
