libata-sff: ata_sff_[dumb_]qc_prep are BMDMA specific
Both qc_prep functions deal only with BMDMA PRD setup and PIO only SFF drivers don't need them. Rename to ata_bmdma_[dumb_]qc_prep() and relocate. All usages are renamed except for pdc_adma and sata_qstor. Those two drivers are not BMDMA drivers and don't need to call BMDMA qc_prep functions. Calls to ata_sff_qc_prep() in the two drivers are removed. Signed-off-by: Tejun Heo <tj@kernel.org> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
