Subject: [PATCH] dt-bindings: PCI: apple: Add missing 'power-domains' property

The 'unevaluatedProperties' schema checks is not fully working and doesn't
catch some cases where there's a $ref to another schema. A fix is pending,
but results in new warnings in examples.

The Apple PCIe host has 3 power domains at least according to the example.
Add the 'power-domains' property to the schema.

Signed-off-by: Rob Herring <robh@...nel.org>

Ideally, we'd define what each power domain is, but I don't know what
they are.
