Subject: [PATCH 3/3] arm64: dts: qcom: talos-evk-camera: Add DT overlay

Enable IMX577 via CCI on Taloss EVK Core Kit.

The Talos EVK board does not include a camera sensor
by default, this overlay reflects the possibility of
attaching an optional camera sensor.
For this reason, the camera sensor configuration is
placed in talos-evk-camera.dtso, rather than
modifying the base talos-evk.dts.
