sata_promise: handle ATAPI_NODATA ourselves
This patch extends sata_promise to handle ATAPI_NODATA commands internally. However, commands destined to ATA_DFLAG_CDB_INTR devices are excluded from this and continue to be returned to libata. Concrete changes: - pdc_atapi_dma_pkt() is renamed to pdc_atapi_pkt(), and is extended to set up correct headers for NODATA packets - pdc_qc_prep() calls pdc_atapi_pkt() for ATAPI_NODATA - pdc_host_intr() handles ATAPI_NODATA - pdc_qc_issue_prot() sends ATAPI_NODATA packets via the chip's packet mechanism, except for CDB_INTR devices Tested on first- and second-generation chips, SATAPI and PATAPI, with no observable regressions.
