480318fb03 Idle the channel earlier in reinit(). 
Cosmetic change to suspend, dont call tsleep an extra time at exit.

f14caa383f Return the unit number of a channel instead of a hardcoded '1' from 
the ATA pccard locking function.  This makes pccard devices like
Compact Flash cards work again.

058a8fa0b8 Move the PC98 specific geometry "gunk" to geom_pc98.c where it belongs. 
This also adds support for bigger disks on the controller I have access to,
and maybe others if I understood the adhoc methods used on those.

Those with more PC98 bigdrive controllers it is hereby invited to add/fix
support for those in geom_pc98.c and not using #ifdef PC98 all over the place.

2fb6fe6a94 Remove the old ATA_*LOCK_CH macros that used atomic ops and use 
mutexes instead.
This closes the last (known) race issues in ATA which should fix
the various hangs etc seen on heavy loaded systems.

Change from using timeout functions to using callout functions in
the timeout code. This together with above closes the race that could
happen if timeout and device interrupt occured simultaniously.

Also fix the possible recursion in ata_reinit() on very dodgy
devices that could take us down in the probe.

7e6d8f0852 Ignore leading '_' in model name returned by devices. 
This make "_NEC" devices appear as "NEC" which is more corrent.
The reason is tha NEC originally screwed up on the byteorder in the
model string, so now that they have realized that they prefixed the '_'
so that not every ATA driver on the planet would call them "EN C" :)

f4de4acfe4 Introduce ata_udelay() that uses tsleep instead of DELAY if possible. 
In places where we have long delays that doesn't depend on too accurate
timing, use ata_udelay() instead of DELAY() so we dont uselessly spin
the CPU if not nessesary;

a33b996095 Refine the wait for ATAPI_RESET. 
Properly wait for not busy and introduce a timeout for devices not
setting busy (as they should).
Leave a printf in there that states how long the wait was, as I'd like
to get an idea of the variations here. The time needed seems also to be
affected by whether a medium is present or not.
