This patch adds callbacks that allow the user to set a new self-defined
CAN channel ID to all USB - CAN/CANFD interfaces of PEAK-System managed by
this driver, namely:
- PCAN-USB
- PCAN-USB FD
- PCAN-USB Pro FD
- PCAN-USB X6
- PCAN-Chip USB
- PCAN-USB Pro

The callback functions write the CAN channel ID to the non-volatile
memory of the devices.
