Remove the Kconfig option for configuring the maximum value of the CAN-FD Data Length Code in order to ensure standard compliance. Allowing users to configure the max DLC allows the user to save a number of bytes per CAN frame in RAM, but it also renders the Zephyr CAN-FD implementation non-compliant with the CAN-FD standard. There are no guarantees that a Zephyr CAN-FD node will not receive a CAN frame with a DLC higher than the Kconfig limit, which opens up for all sorts of bugs when trying to handle received CAN-FD frames.
