Subject: [PATCH 1/4] scsi:stex.c Support to Pegasus series.

Pegasus is a high performace hardware RAID solution designed to unleash
the raw power of Thunderbolt technology.

I add code to distinct SuperTrack and Pegasus series by subID.
It's needed for backward compatibility.

Change the driver version.
