From: Jim Lin jilin@nvidia.com
Add support for command line "usb reset" or "usb start" to initialize , "usb stop" to stop multiple USB controllers at once. Other commands like "usb tree" also support multiple controllers.
New added definitions in header file are: CONFIG_USB_INIT_MULTI CONFIG_USB_MAX_CONTROLLER_COUNT
