Scott Long 5974e5c71c Refactor the bus_dma header files so that the interface is described in
sys/bus_dma.h instead of being copied in every single arch.  This slightly
reorders a flag that was specific to AXP and thus changes the ABI there.
The interface still relies on bus_space definitions found in <machine/bus.h>
so it cannot be included on its own yet, but that will be fixed at a later
date.  Add an MD <machine/bus_dma.h> for ever arch for consistency and to
allow for future MD augmentation of the API.  sparc64 makes heavy use of
this right now due to its different bus_dma implemenation.
