This commit adds option for Teensy 4.x board to initialize CAN3 as can0. The reason of this is the CAN FD capability of CAN3. This commit also disables tickless mode support for pikron-bb configuration as this option started causing hard faults which are yet to be solved. Signed-off-by: Michal Lenc <michallenc@seznam.cz>
