 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
