OK, I managed to code and test this. Have a look at the attached. It
combines both the raid device exposure and the DV code (the patches got
rather hopelessly entangled while I worked on them).
This is what we now show for a RAID device with the underlying physical
disks appearing on the virtual channel:
mptbase: Initiating ioc0 bringup

scsi7 : ioc0: LSI53C1030, FwRev=01032920h, Ports=1, MaxQ=222, IRQ=57

And this is what happens if I remove and reinsert one of the RAID
devices:
target7:1:1: Integrated RAID requests DV of new device
target7:1:1: Beginning Domain Validation
target7:1:1: Domain Validation skipping write tests
target7:1:1: Ending Domain Validation
target7:1:1: FAST-40 WIDE SCSI 80.0 MB/s ST (25 ns, offset 31)
I also added back the RAID quiesce that the old code did while
performing DV.
