can: peak_usb: export pcan_usb_pro functions
Add support for the following new PEAK-System technik CANFD USB adapters: PCAN-USB FD single CANFD channel USB adapter PCAN-USB Pro FD dual CANFD channels USB adapter The communication protocol has been developed using some mechanisms that did exist in the PCAN-USB Pro, thus, this patch also changes some previously static functions and data into global ones.
