[PATCH] ARM: shmobile: porter: add CAN0 DT support

[Sergei Shtylyov]

Define the Porter board dependent part of the CAN0 device node.

This patch is  analogous to the commit 457acc4a6ce8 (ARM: shmobile:
henninger: add CAN0 DT support) as there are no differences between the
boards in this respect.
