[PATCH 3/4] arm64: dts: qcom: monaco-evk-camera: Add DT overlay

[Vikram Sharma <quic_vikramsa@quicinc.com>]

From: Nihal Kumar Gupta <quic_nihalkum@quicinc.com>

Enable IMX577 sensor using the CCI1 interface on Monaco EVK.
Camera reset is controlled through an I2C expander,
and power supply is managed via tlmm GPIO74.
