[SCSI] mptspi: Add transport class Domain Validation
This is the first half of a patch to add the generic domain validation
to mptspi. It also creates a secondary "virtual" channel for raid
component devices since these are now exported with no_uld_attach.
What Eric and I would have really liked is to export all physical
components on channel 0 and all raid components on channel 1.
Unfortunately, this would result in device renumbering on platforms with
mixed RAID/Physical devices which was considered unacceptable for
userland stability reasons.
Still to be done is to plug back the extra parameter setting and DV
pieces on reset and hotplug.
