ARM: 8023/1: remove remnants of the static DMA mapping

Browse Source 
It looks like the static mapping area for DMA was replaced by dynamic
allocation into the vmalloc area by commit e9da6e9905 but the
information in Documentation/arm/memory.txt was not removed accordingly.

CONSISTENT_END in arch/arm/include/asm/memory.h has no more users and
can be removed as well.
