[PATCH v3 02/12] dt-bindings: media: qcom,glymur-iris: Add glymur video codec

[Vishnu Reddy]

Add device tree binding for the Qualcomm Glymur Iris video codec. Glymur
is a new generation of video IP that introduces a dual-core architecture.
The second core brings its own power domain, clocks, and reset lines,
requiring additional power domains and clocks in the power sequence.

To accommodate glymur clock and power resources requirement, the maxItems
constraints in qcom,venus-common.yaml are relaxed. This allows the glymur
binding to inherit from the common venus schema without duplicating shared
properties.
