dt-bindings: usb: ci-hdrc-usb2: Allow "fsl,imx27-usb" to be passed alone

From: Fabio Estevam <[email protected]>

imx27.dtsi describes its usb nodes as:

compatible = "fsl,imx27-usb";

Adjust the bindings to allow it and avoid the following schema warning:

usb@10024000: compatible: 'oneOf' conditional failed, one must be fixed:

	['fsl,imx27-usb'] is too short

This probably could go with a fixes tag. In any case:
