[PATCH v3 7/8] usb: cdns3-ti: add J7200 support with reset-on-resume behavior

[Théo Lebrun]

Add ti,j7200-usb compatible. Match data indicates the controller resets
on resume meaning:
 - The cdns3-ti wrapper init sequence must be ran at resume.
 - Tell the cdns3 core that we reset on resume. This silences a xHCI
   warning visible in cases of unexpected resets.
