[PATCH 3/6] libata: map UDMA protocols

[Albert Lee <albertcc@tw.ibm.com>]

Patch 3/6:
 Map the ATA passthru UDMA protocols to ATA_PROT_DMA.

Don't know why SAT distinguishs "UDMA Data In" and "UDMA Data Out" from "DMA".
These UDMA protocols only matter for on-the-wire-protocol and are mostly transparent
to the software. Anyway, map both of UDMA protocols to "ATA_PROT_DMA" here.
