cangw: support len8_dlc for Classical CAN frames

Browse Source 
The can_dlc value that is passed to the kernel is not sanitized in cangw
therefore we only update the help text and some comments in gw.h.

In the case that the CAN interface supports len8_dlc by setting
CAN_CTRLMODE_CC_LEN8_DLC the can-gw module can modify the full DLC value
range (0 .. 15) for Classic CAN frames.
