can: peak_usb: add callback to read CAN channel ID of PEAK CAN-FD devices

Browse source

This patch adds a new function that allows to read the CAN channel ID
from the non volatile memory of the USB CAN-FD PEAK devices. The CAN
channel ID is a user-configurable u8/u32 identifier value that can be set
individually for each PEAK CAN interface.
