I'm not sure what the best way to fix this one is... The ideal way is to
change ipr to select CONFIG_ATA, but kconfig currently doesn't handle
that and complains about recursive dependencies since IPR depends on
CONFIG_SCSI and CONFIG_ATA selects CONFIG_SCSI. I'm guessing the
libsas SATA usage has similar problems. Right now we both use a depends
CONFIG_ATA statement. Ideally, kconfig should be fixed to handle this.
