According to the schematics, the CAN transceiver is connected to pins
GP7_3 and GP7_4, which correspond to CAN0 data group B.

Fixes: 0768fbad7fba1d27 ("ARM: shmobile: porter: add CAN0 DT support")
Signed-off-by: Geert Uytterhoeven <geert+renesas at glider.be>

Untested due to lack of hardware.
I did verify that the CAN0 bits in the pfc driver match the
documentation.
