    SILI - Work around hardware LRAM bugs part 2/2.
    * Add ATA_F_AUTOSENSE and ATA_F_EXCLUSIVE to deal with accessing the
      D2H RFIS.
      ATA_F_AUTOSENSE tells sili.c that the caller wants to access the rfis.
      The sili core is then responsible for copying the rfis out of the LRAM
      and into host-memory.
      ATA_F_EXCLUSIVE tells sili.c that the caller wants to be the only
      command queued to the chip for that particular command.
    * Currently ATA_F_AUTOSENSE implies ATA_F_EXCLUSIVE, but ultimately we will
      want to do the auto-sense as a separate step so things like ATAPI farms
      can run commands in parallel.
