fix spelling mistakes, mainly in comments and log messages.

Fix style and typo in comments. No binary changes.

Remove closes 3 & 4 from my licence. Lots of thanks to Soren Jacobsen
for the booring work !

Convert many of the uses of __attribute__ to equivalent
__packed, __unused and __dead macros from cdefs.h

branches: 1.13.46; 1.13.52; 1.13.56; 1.13.60;
merge ktrace-lwp.

branches: 1.12.4;
nuke trailing whitespace

branches: 1.11.8; 1.11.10;
Remove references to University of California from my copyright notices.

branches: 1.10.2;
Correct setup of General Purpose Register for PDC20265 (Ultra/100) and newer.
From Andreas Johansson in private mail.

Make DMA mode works on Promise Ultra66/100 with 48-bit LBA drives.
Ok'ed by bouyer in tech-kern@netbsd.org.

Spell '[Rr]ight' correctly. From Jim Bernard.

branches: 1.7.2; 1.7.4;
More copyright fixes, pointed out by Thomas. Thanks !

Make the various timing, etc. tables const, and add the __unused__
attribute to them, just in case something other than the pciide driver
proper needs to pull in the header.

branches: 1.5.2;
Fix typo. s/extention/extension/

Correct definition of PDC262_U66_EN (from FreeBSD).
Correct values of MW DMA 2, and add values for UDMA5 (from linux).

branches: 1.3.4; 1.3.6; 1.3.8;
Sync my copyrigth notice.

Improve Ultra/66 support now that I've got some docs from Promise.

branches: 1.1.2; 1.1.8;
Add support for the Promise Ultra/33 and /66 pci IDE controller. In addition to
chip-dependant code this required the following changes:
- Instead of attaching the device in a generic way with some chip-dependant
routines, use a chip-dependant attach routine with some common code
factored out. The code is marginally bigger, but this allows the CMD64x
flag hack to go away.
- For chips that report per-channel 'irq triggered', test this before calling
wdcintr() for the native-pci irq case (compat intr can't be shared),
as wdcintr() has no good way to know if a irq was for it or not, and
ends up with irq loss. XXX for chips that don't have this feature irq sharing
will not work properly !
- add my copyrigth notice (could have been done some time ago I think :)

There are still some issues to be solved with the Promise controller and
ATAPI devices.
Many thanks to Paul Newhouse for shipping me 2 Ultra/33 boards for doing this
work.
