Bring back bus_dmasync_op_t. It is now a typedef to an int, though the
...
BUS_DMASYNC_ definitions remain as before. The does not change the ABI,
and reverts the API to be a bit more compatible and flexible. This has
survived a full 'make universe'.

- Convert NetBSD-derived macros to inline functions for better
...
type-checking and future debug code.
- Remove sparse addressing hack, since the only consumer, the macio ATA
driver, doesn't require it anymore.

I deserve a big pointy hat for having missed all those references

to bus_dmasync_op_t in my last commit.

Correctly set BUS_SPACE_MAXSIZE in all the busdma backends.
...
It was bogusly set to 64 * 1024 or 128 * 1024 because it was
bogusly reused in the BUS_DMAMAP_NSEGS definition.

Rework of how memory resources are discovered and dealt with in macio.
...
- Store the OpenFirmware "reg" property in the macio ivars.
- Use a struct to define the structure of a "reg" property entry.
- Discover all memory ranges, not just the first.
- In ata_macio, manage our own range and hand out our own allocations using
bus_space_subregion.
- Fix bus_space_subregion to handle subregions of sparse maps.

1) Add busdma machdep code.
...
2) Add bus_pio.h and bus_memio.h (which do nothing).
