Since commit 6f3b911d5f29b98 ("can: bcm: add support for CAN FD frames") the
CAN broadcast manager supports CAN and CAN FD data frames.

As these data frames are embedded in struct can[fd]_frames which have a
different length the access to the provided array of CAN frames became
dependend of op->cfsiz. By using a struct canfd_frame pointer for the array of
CAN frames the new offset calculation based on op->cfsiz was accidently applied
to CAN FD frame element lengths.

This fix makes the pointer to the arrays of the different CAN frame types a
void pointer so that the offset calculation in bytes accesses the correct CAN
frame elements.
