[U-Boot] [PATCH 1/2] Add minimal SJA1000 header for basic CAN mode

[Matthias Fuchs <matthias.fuchs@esd.eu>]

Wolfgang,

can you please apply this patch. It currently prevents Stefan
to proceed with my other 4xx patches. Alternatively this
could be done by Stefan through the 4xx repo.

Regards,
Matthias
