libata: Strict checking for identify reporting
The ATA specifications require checks on certain flags before assuming the validity of other data. Go through the methods and correct those needing extra checks. Also note limits on ata_id_major_version with respect to ATA-1 and ATA-2. Correct the 32bit PIO check. Wants to sit in -mm for a bit in case of a screwup on my part that I didn't hit on the test drives and also in case someone, somewhere has a drive that gets it wrong.
