Need to reference pci-bus.yaml.

Drop these, pci-bus.yaml covers them.

Just 'maxItems: 1'. No need for generic descriptions.

*-supply is not an array.

maxItems: 1

Add 'maxItems: 1' as *-gpios is an array.

Can drop.

Can drop.

Can drop everything pci-bus.yaml says is required.

Will need to be 'unevaluatedProperties: false' with pci-bus.yaml 
referenced.
