[U-Boot] [PATCH 1/6] usb : musb : Add high speed field in usb_device structure

[Thomas Abraham]

This patch adds support for identification of high speed devices.
For high spped devices that are connected via hubs, the information
that the device is high speed is recorded. This is required by Mentor
USB Host controller driver.
