Subject: arm64: dts: qcom: sc8280xp: add missing PCIe minimum OPP
From: Johan Hovold <johan+linaro@xxxxxxxxxx>
commit 8b8ec83a1d7d3b6605d9163d2e306971295a4ce8 upstream.
Add the missing PCIe CX performance level votes to avoid relying on
other drivers (e.g. USB or UFS) to maintain the nominal performance
level required for Gen3 speeds.
