sata_mv: fix broken DSM/TRIM support (v2)
commit 44b733809a5aba7f6b15a548d31a56d25bf3851c upstream.
Fix DSM/TRIM commands in sata_mv (v2).
These need to be issued using old-school "BM DMA",
rather than via the EDMA host queue.
Since the chips don't have proper BM DMA status,
we need to be more careful with setting the ATA_DMA_INTR bit,
since DSM/TRIM often has a long delay between "DMA complete"
and "command complete".
GEN_I chips don't have BM DMA, so no TRIM for them.
