Allocate separate USB buffers for DMA'ed data, so that
DMA data does not reside next to non DMA data. This
might cause more memory to be allocated, but solves
problems on platforms using manual cache
synchronization.

Add a convenience function to get the buffer only
from a USB transfer's page cache structure.
