dt-bindings: usb: snps,dwc3: Allow power-domains property
The Rockchip RK3399 DWC3 node has 'power-domains' property which isn't allowed by the schema: usb@fe900000: Unevaluated properties are not allowed ('power-domains' was unexpected) Allow DWC3 nodes to have a power-domains entry. We could instead move the power-domains property to the parent wrapper node, but the could be an ABI break (Linux shouldn't care). Also, we don't want to encourage the pattern of wrapper nodes just to define resources such as clocks, resets, power-domains, etc. when not necessary.
