Had to move the RTC area for ATC board to upper addresses

(0xf5000000, to be specific). The reason is that the RTC first gets
accessed before MMU is initialized and, consequently, it needs to be
placed at physical addresses which are later mapped to the same
virtual addresses (like 0xf5000000 physical is mapped to 0xf5000000
virtual).
