[RFC/RFT 0/2] ARM: mm: Introduce arch hooks for dma address translation

Currently arch specific DMA address translation routines can be enabled
using only defines wtth "mach/memory.h" which makes impossible to use them
in with multi-platform, single zImage builds.

Hence, introduce arch specific hooks for DMA address translations
routines to be compatible with multi-platform builds. In case if
an architecture won't use it - DMA address translation routines
will fall-back to existing implementation.

Series updates existing machines like omap1, ks8695, iop13xx to
use new DMA hooks.
