From: Johan Hovold <johan+linaro@xxxxxxxxxx>
commit 98abf2fbd179017833c38edc9f3b587c69d07e2a upstream.
Add the missing PCIe CX performance level votes to avoid relying on
other drivers (e.g. USB) to maintain the nominal performance level
required for Gen3 speeds.
Fixes: 5eb83fc10289 ("arm64: dts: qcom: x1e80100: Add PCIe nodes")
