ARM: dts: stm32: add CAN support on stm32f429
commit 7355ad1950f41e755e6dc451834be3b94f82acd4 Linux upstream. Add support for bxcan (Basic eXtended CAN controller) to STM32F429. The chip contains two CAN peripherals, CAN1 the primary and CAN2 the secondary, that share some of the required logic like clock and filters. This means that the secondary CAN can't be used without the primary CAN.
