[SCSI] add preliminary expander support to the sas transport class
This patch makes expanders appear as labelled objects with properties in
the SAS tree.
I've also modified the phy code to make expander phys appear labelled by
host number, expander number and phy index.
So, for my current config, you see something like this in sysfs:
/sys/class/scsi_host/host1/device/phy-1:4/expander-1:0/phy-1-0:12/rphy-1:0-12/target1:0:1
And the expander properties are:
jejb@sparkweed> cd /sys/class/sas_expander/expander-1\:0/
jejb@sparkweed> for f in *; do echo -n $f ": "; cat $f; done
