Subject: [PATCH] arm64: dts: qcom: sc8280xp-x13s: Enable RGB sensor

Enable the main RGB sensor on the Lenovo x13s a five megapixel 2 lane DPHY
MIPI sensor connected to cisphy0.

With the pm8008 patches recently applied to the x13s dtsi we can now also
enable the RGB sensor. Once done we have all upstream support necessary for
the RGB sensor on x13s.
