[RFC PATCH 1/1] dt-bindings: connector: Add role‑switch provider phandle

[Elson Serrao <elson.serrao@oss.qualcomm.com>]

Add an optional consumer→provider phandle on USB connectors to reference
the USB role-switch provider when no direct graph link exists. The DRD
controller remains the provider via its 'usb-role-switch' property.
