[PATCH v6 4/9] dt-bindings: usb: add NXP ChipIdea USB2 Controller schema

[Xu Yang]

As more and more NXP i.MX chips come out, it becomes harder to maintain
ci-hdrc-usb2.yaml if more stuffs like property restrictions are added to
this file. This will separate i.MX parts out of ci-hdrc-usb2.yaml and add
a new schema for NXP ChipIdea USB2 Controller.
