[PATCH v9 5/5] arm64: dts: qcom: shikra-iqs-evk-imx577-camera: Add DT overlay for Shikra

[Nihal Kumar Gupta]

Shikra IQS is an industrial-grade variant using PM8150 PMIC, requiring
different CSIPHY and sensor supply rails compared to the retail boards
(CQM and CQS) which use PM4125.

Add a dedicated overlay for optional IMX577 integration via CSIPHY1.
