ata_piix: convert to prepare - activate initialization
libata: factor out ata_pci_activate_sff_host() from ata_pci_one()
[libata] Prefer SCSI_SENSE_BUFFERSIZE to sizeof()
pata_legacy: resychronize with upstream changes and resubmit
[libata] pata_legacy: typo fix
[libata] pata_winbond: update for new ->data_xfer hook
pata_pcmcia: convert to new data_xfer prototype
