Subject: [PATCH v4 03/12] dt-bindings: gpu: mali-bifrost: Fix power-domain-names validation

Commit ("dt-bindings: gpu: mali-bifrost: Add Mediatek MT8183")
incorrectly introduced power domain names for MT8183, causing
validation issues.

Add power-domain-names to the base schema, allowing a maximum of
five elements; since platforms having a single power domain don't
need any actual domain name, disallow that for each sub-schema.

Fixes: a7a596cd3115 ("dt-bindings: gpu: mali-bifrost: Add Mediatek MT8183")
