Since the minimum/maximum supported bitrates are now stored in the common CAN controller driver configuration struct, retrieving these can no longer fail. Add new CAN controller API functions can_get_bitrate_min() and can_get_bitrate_max() reflecting this and deprecate the existing can_get_min_bitrate() and can_get_max_bitrate().
