jtag: drivers: provide initial support for usb path filtering

Browse Source 
With this patch drivers will be able to use usb path filtering.
The path format is identical to the format provided by linux kernel:
bus-port.port....
With this format it should be easier just to copy and paste
path found in dmesg.
