[PATCH v2 11/14] dt-bindings: media: qcom,qcm2290-camss: Add OPE ISP subnode

[Loic Poulain]

Extend the qcm2290 CAMSS binding to describe CAMSS as a simple bus by
allowing child ISP nodes. Add the required address and size cells, as
well as ranges, and validate ISP subnodes against the existing
qcom,qcm2290-camss-ope schema.

On qcm2290 the OPE (Offline Processing Engine) is a memory-to-memory
ISP (Image Signal Processor).
