Subject: [PATCH] dt-bindings: media: qcom: Add Shikra CAMSS compatible

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.
