arm64: dts: qcom: talos-evk-camera: Add DT overlay

Enable IMX577 via CCI on Talos EVK Core Kit.

The Talos EVK board does not include a camera sensor
by default. This DTSO has enabled the Arducam 12.3MP
IMX577 Mini Camera Module on the CSI-1 interface.
CSI-1 interface using mclk2 as the MCLK source on this board.
