Add support for the newly available esd CAN-USB/3.
The USB protocol for the CAN-USB/3 is similar to the protocol used for
the CAN-USB/2 and the CAN-USB/Micro, so most of the code can be shared
for all three platforms. Most work simply arises from the fact, that
the CAN-USB/3 is capable of handling CAN FD frames.
The main job is to
* also probe for an esd CAN-USB/3
* extend USB structures for CAN FD data
* allow esd_usb_rx_can_msg() and esd_usb_start_xmit() to handle
CAN FD frames
* spend structures and functionality for setting a CAN FD
bittiming
