ARM: dts: stm32: add pin map for CAN controller on stm32f4

Browse Source 
commit 559a6e75b4bcf0fc9e41d34865e72cf742f67d8e Linux upstream.

Add pin configurations for using CAN controller on stm32f469-disco
board. They are located on the Arduino compatible connector CN5 (CAN1)
and on the extension connector CN12 (CAN2).
