arm64: dts: qcom: lemans-evk: Add IMX577-based camera overlay

Enable IMX577 via CCI1 on LeMans EVK Core Kit.

The LeMans 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 lemans-evk-camera.dtso, rather than
modifying the base lemans-evk.dts.
