[ARM] 5295/1: make ZONE_DMA optional
Most ARM machines don't need a special "DMA" memory zone, and
when configured out, the kernel becomes a bit smaller:
| text data bss dec hex filename
|
3826182 102384 111700
4040266 3da64a vmlinux
|
3823593 101616 111700
4036909 3d992d vmlinux.nodmazone
This is because the system now has only one zone total which effect is
to optimize away many conditionals in page allocation paths.
So let's configure this zone only on machines that need split zones.

The dmabounce dma_sync_xxx() implementation have been broken for

the CPU visible buffer no irrespective of the change of ownership.
(IOW, a DMA_FROM_DEVICE mapping copies data from the DMA buffer
to the CPU buffer during a call to dma_sync_single_for_device().)
Fix it by getting rid of sync_single(), moving the contents into

appropriately.
