Log Message:
Fix kernel dump on ahci controller, by making sure we won't sleep
while dumping:
- introduce ata_delay() which either use delay() or kpause()
  depending on flags. use it in sata_reset_interface() and
  some ahci functions
- kill ATA_NOSLEEP, it was tested but never set. use ATA_POLL instead.
- reduce delay while polling in ahci, to speed up the dump

Should fix PR kern/41095
