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.
