Based on a quick look at sata_mv it appears it sets a 64-bit DMA mask
unconditionally, but for non-ATA_PROT_DMA commands (which includes all
ATAPI), it just falls back to ata_qc_issue_prot which issues via the
legacy SFF interface and can only handle 32-bit addressing. So yes, it
appears to have a similar bug as sata_nv had.
sata_mv doesn't do ATAPI at all...
