 cpu/armv7m: Fix initialization of MPU regions

 The write to RBAR didn't have the valid flag set. Therefore the write to
 RASR had an influence on the previously set region. That means for
 example that if Region 0 had been enabled but 1 should be disabled due
 to a size of 0, the previous code would have disabled region 0 instead.

 This patch fixes that behaviour.
