The Marvell bridge chips used on HighPoint SATA cards do not seem to support
the MWDMA modes (at least that caould be seen in their so-called drivers :-),
so the driver needs to account for this -- to achieve this:
- add mdma_filter() method from the original patch by Bartlomiej Zolnierkewicz
with his consent,
also adding the method callout to ide_rate_filter();
- install the method for all chips to only return empty mask if a SATA drive
is detected on HPT372{AN]/374 chips...
