Driver panic when RAID logical volume was present when driver
loaded, or when a RAID logical volume was created on the fly.
This issue was created in due to recent scsi_transport_sas change,
when sas_read_port_mode_page was added into the mptsas drivers
slave_config entry point.
This new API expects that all sdev's to be assocated to an rphy, however
that is not the case for logical volumes, as they are created using
scsi_add_device, instead of sas_rphy_add().

This adds support for hot adding and removing
expanders, and its associated attached devices.
When there is a change in topology,
the fusion firmware sends the
MPI_EVENT_SAS_DISCOVERY event to the driver.
The driver will read firmware config pages
to determine what changes took place, and refresh
drivers view of the world stored in ioc->sas_topology.
Here is the details of the action the driver does:
(1) Expander Added : The mptsas_discovery_work
workqueue is called. Config pages read, and
ioc->sas_topology is refreshed. The sas_phy_add()
is called for each phy of the expander. The
expanders attached devices are added via
sas_rphy_add(). Added end devices are handled within
the MPT_ADD_DEVICE logic in mptsas_hotplug_work
workqueue.
(2) Expander Delete : The sas_rphy_delete() will be
called for the top most compenent of the parent that the
expander is attached to. The sas_rphy_delete call
will delete all the children phys, rphys, and end devices.
This is handled from mptsas_discovery_work workqueue.

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.
