usb: Add USB 3.1 Precision time measurement capability descriptor support
commit faee822c5a7ab99de25cd34fcde3f8d37b6b9923 upstream.
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.
