sata_mv: workaround for multi_count errata sata24
Workaround for errata SATA#24 in sata_mv.
This errata affects WRITE_MULTI* commands when
the device multi_count produces a DRQ block size >= 4Kbytes.
We work around it here by converting such operations
into ordinary PIO_WRITEs instead.
Note that this might result in a PIO FUA write unavoidably being converted
into a non-FUA write. In practice, any system using FUA is also going to be
using DMA rather than PIO, so this shouldn't affect anyone in the real world.
