PATCH 1/1 sata_qstor: new basic driver for Pacific Digital QStor

This is a new basic libata SATA driver
for the Pacific Digital QStor SATA/RAID card.

It features ordinary per-drive SATA with single-request DMA for R/W commands, and PIO for everything else.

It currently does not implement any of the hardware RAID support, nor hot-plug, nor the tagged/native command-queuing features.

On the other hand, it is small and simple as a result.

Patch is against 2.6.11-rc4 + minor libata updates from Jeff.
