usb: Add USB 3.1 Precision time measurement capability descriptor support
USB 3.1 devices that support precision time measurement have an additional PTM cabaility descriptor as part of the full BOS descriptor Look for this descriptor while parsing the BOS descriptor, and store it in struct usb_hub_bos if it exists.
