is this part related to sama5d4ek or is it a generic fix? Could yopu
please send as an extra patch if it's the latter?

I wonder if we should introduce H32MXDIV for all atmel SoC and remove
the CPU_HAS_H32MXDIV here. A division by 1 should be optimized away if
it is a constant. After all this piece of code would be more readable.
