[PATCH v4 02/18] dt-bindings: gpu: img: Add BXS-4-64 devicetree bindings

[Matt Coster]

Unlike AXE-1-16M, BXS-4-64 uses two power domains.

Like the existing AXE-1-16M integration, BXS-4-64 uses the single clock
integration in the TI k3-j721s2.

Changes in v4:
- Add minItems: 1 to power-domain-names so we don't break single domain
  bindings
- Add back power-domains to conditional constraints to match
  power-domain-names
- Link to v3: https://lore.kernel.org/r/20250310-sets-bxs-4-64-patch-v1-v3-2-143b3dbef02f@imgtec.com
Changes in v3:
- Include adding the second power domain so it's in context
- Remove unnecessary example
- Link to v2: https://lore.kernel.org/r/20241118-sets-bxs-4-64-patch-v1-v2-8-3fd45d9fb0cf@imgtec.com
Changes in v2:
- Use normal reg syntax for 64-bit values
- Link to v1: https://lore.kernel.org/r/20241105-sets-bxs-4-64-patch-v1-v1-8-4ed30e865892@imgtec.com
