Scatter/gather DMA mode works nicely on this platform and is clearly the
best way of doing things.

The core driver can now operate in either vmalloc or dma-contig modes;
obviously the latter is preferable when it is supported. Default is
currently vmalloc on all platforms; load the module with buffer_mode=1 for
contiguous DMA mode.

Now we have a camera working over the marvell cam controller core. It
works like the cafe driver and has all the same limitations, contiguous DMA
only being one of them. But it's a start.
