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

Monaco EVK board does not include a camera sensor in its default hardware
configuration. Introducing a device tree overlay to support optional
integration of the IMX577 sensor via CSIPHY1.

Camera reset is handled through an I2C expander, and power is enabled
via TLMM GPIO74.

An example media-ctl pipeline for the imx577 is:

media-ctl --reset
media-ctl -V '"imx577 3-001a":0[fmt:SRGGB10/4056x3040 field:none]'
media-ctl -V '"msm_csiphy1":0[fmt:SRGGB10/4056x3040]'
media-ctl -V '"msm_csid0":0[fmt:SRGGB10/4056x3040]'
media-ctl -V '"msm_vfe0_rdi0":0[fmt:SRGGB10/4056x3040]'
media-ctl -l '"msm_csiphy1":1->"msm_csid0":0[1]'
media-ctl -l '"msm_csid0":1->"msm_vfe0_rdi0":0[1]'
yavta -B capture-mplane -c -I -n 5 -f SRGGB10P -s 4056x3040 -F /dev/video1
