[PATCH v3 5/6] arm64: dts: qcom: shikra-cqm-cqs-evk-imx577-camera: Add DT overlay

[Nihal Kumar Gupta]

Shikra CQM and CQS are retail variants sharing the same PM4125 PMIC
and identical camera supply rails. The only difference between them
is the integrated modem on CQM, which does not affect camera hardware.

Add a shared overlay for optional IMX577 integration via CSIPHY1,
used by both CQM and CQS EVK boards.
