These options make it possible to overwrites the data and instruction
prefetching behavior of the arm pl310 cache controller.

We have to set these values in the aux and the prefetch register,
because these two bits in the aux registers are mapped to the prefetch
register. If only the prefetch register is changed there is an
inconsistence in the state in this driver.

No there isn't.  Just set the bits in the prefetch register.

Writing to the prefetch register changes the state of the bits in the
auxiliary control register at the same time.
