pvrusb2: Generate a device-unique identifier
From: Mike Isely <isely@pobox.com>
Implement a new internal function to create a string device
identifier. This ID stays with the specific device, making it useful
to user space to identify specific devices. We use the serial number
if available; otherwise we give up and just spit out a unit/instance ID.
