[PATCH 2/4] arm64: dts: qcom: sc8280xp-crd: Introduce pmic_glink

[Bjorn Andersson]

From: Bjorn Andersson <bjorn.andersson at linaro.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.
