drivers: call adapter_get_required_serial() in jtag_libusb_open()

Now that adapter serial is handled independently from the adapter
drivers, move inside jtag_libusb_open() the call to
adapter_get_required_serial(), so every adapter that uses libusb
will automagically get USB serial support.

Extend the documentation to list the adapters involved.
