Modified Files:
        src/sys/dev/ic [jdolecek-ncq]: siisata.c

Log Message:
convert over to new error handling world order:
- switch to ata_timeout()
- stop using ch_status/ch_error for passing state/error, stop setting
  ATACH_IRQ_WAIT in ch_flags; pass the state via the last parameter
  to c_intr() routine
- add NCQ recovery and KILL_REQUEUE
- only call atastart() in c_intr() if there was no error

several siisata specific tweaks:
- improve reset to better handle PM - need to reset couple more registers
- add timeouts for unbusy wait - ATA_DELAY (10s)
- siisata_bio_complete() do not use PRSO_RTC for byte count for NCQ transfers,
  they never return partial reads; and that register might contain some random
  junk, at least that's the case with ahcisata cmdh_prdbc
