ATA6r1 and ATA6r3, which caused drives conform to ATA6r3 or later to reject LBA28 commands at sector 0xfffffff. Get the right idea from the LBA48 boundary from IDENTIFY words 60-61. Remove the WD_QUIRK_FORCE_LBA48 quirk, associated tables entries and autodetect code, it's not needed any more. Based on patch sent to teck-kern by Christoph Badura, use of words 60-61 instead of a constant for the LBA48 boundary by me.
