arm/km: fix memory settings
On kmcoge5un we faced some serious problems with the memory during temperature tests. Reason was that we overwrite some registers for memory settings which have to leave untouched. These where registers 0x20148 , 0x2014c and 0x20154. So writing these registers is prohibited and this patch removes them from all km related config files. Even if the problem was only seen on kmcoge5un.
