Subject: [PATCH v2 2/4] arm64: dts: qcom: sc8280xp-crd: Introduce pmic_glink
From: Bjorn Andersson <bjorn.andersson@...aro.org>
The SC8280XP CRD control over battery management and its two USB Type-C
port using pmic_glink and two GPIO-based SBU muxes.
Enable the two DisplayPort instances, GPIO SBU mux instance and
pmic_glink with the two connectors on the CRD.

Changes since v1:
- Fixed style and property sort issues
- Moved dwc3/port to sc8280xp.dtsi, override remote-endpoint here
- Added pinconf properties to SBU control pins
