[SCSI] Migrate libsas ATA code into a separate file
This is a respin of my earlier patch that migrates the ATA support code into a separate file. For now, the controversial linking bits have been removed per James Bottomley's request for a patch that contains only the migration diffs, which means that libsas continues to require libata. I intend to address that problem in a separate patch. This patch is against the aic94xx-sas-2.6 git tree, and it has been sanity tested on my x206m with Seagate SATA and SAS disks without uncovering any new problems. Signed-off-by: Darrick J.
