Subject: [PATCH v4 2/8] dt-bindings: display/msm: gpu: Simplify conditional
 schema logic

JSON Schema conditionals can become complex and error-prone when combined
with regex patterns. To improve readability and maintainability, replace
nested if-else blocks with a flattened structure using explicit enums.
