can: flexcan: use be32_to_cpup to handle the value of dt entry
The freescale arm i.MX series platform can support this driver, and usually the arm cpu works in the little endian mode by default, while device tree entry value is stored in big endian format, we should use be32_to_cpup() to handle them, after modification, it can work well both on the le cpu and be cpu.
