Use dma_addr_t type for scatter/gather code

This patch uses the newly created dma_addr_t type throughout the
scatter/gather handling code in dma-helpers.c whenever we need to
represent a dma bus address.  This makes a better distinction as to
what is a bus address and what is a cpu physical address.  Since we
don't support IOMMUs yet, they can't be very different for now, but
that will change in future, and this preliminary helps clarify what's
going on.
