Subject: [PATCH v2 1/7] dt-bindings: usb: ti,j721e-usb: add ti,j7200-usb
 compatible

On this platform, the controller & its wrapper are reset on resume. This
makes it have a different behavior from other platforms.

We allow using the new compatible with a fallback onto the original
ti,j721e-usb compatible. We therefore allow using an older kernel with
a more recent devicetree.
