Add Shikra compatible consistent with CAMSS CCI interfaces. It requires only two clocks.

Shikra contains the same Camera Subsystem IP as QCM2290. Document the platform-specific compatible string, using qcom,qcm2290-camss as fallback. Unlike QCM2290, Shikra omits the CDM and OPE blocks, requiring only a single IOMMU context bank instead of four.

Add the Camera Subsystem node. Shikra shares the same IP as QCM2290 with two CSIPHYs, two CSIDs and two VFEs, but does not include CDM and OPE blocks, so only a single IOMMU context bank is needed.

…overlay 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.

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.

Updated shikra patches:
Shikra EVK is based on the Qualcomm Shikra SoC.
It lacks a camera sensor in its default configuration.
This series adds CAMSS driver support, CCI definitions and enables
the 22-pin IMX577 sensor via CSIPHY0 through a device tree overlay.
We have tested IMX577 Sensor on CCI1 with following commands using yavta and libcamera:
media-ctl --reset
media-ctl -d /dev/media0 -V '"imx577 1-001a":0[fmt:SRGGB10/4056x3040 field:none]'
media-ctl -d /dev/media0 -V '"msm_csiphy1":0[fmt:SRGGB10/4056x3040]'
