[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. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
