Clean up siisata pci attachment.
noteable changes:
- Use aprint_*_dev where appropriate.
- Condense board match table and use C99 initializers.
- Use aprint_verbose for extra info.
Also, add 2009 to my copyright, as well as remove my local CVS tags.
- Support detachment. From KIYOHARA Takashi.
- Add PCI detachment functionality (albeit not very interesting when
the bus can not yet be rescanned).
- Rework interrupt handlers to reduce near-duplicate code.
Borrowed from ahcisata(4).
- Attempt to make polled I/O work. Untested.
- Fix formatting of some messages.
- For always-polled commands, disable interrupt
at slot level rather than port level.
- Instead of busy-waiting indefinitely for completion of some commands
move on after 31 seconds. Use cv_timedwait(9) instead of DELAY(9).
- Use abstracted SATA FIS code.
- Enable use of disks that don't respond with the standard signature.
