cciss: add cciss driver sysfs entries
Add sysfs entries to the cciss driver needed for the dm/multipath tools.
A file for vendor, model, rev, and unique_id is added for each logical
drive under directory /sys/bus/pci/devices/<dev>/ccissX/cXdY. Where X =
the controller (or host) number and Y is the logical drive number.
A link from /sys/bus/pci/devices/<dev>/ccissX/cXdY/block:cciss!cXdY to
/sys/block/cciss!cXdY/device is also created. A bus is created in
/sys/bus/cciss. A link is created from the pci ccissX entry to
/sys/bus/cciss/devices/ccissX. Please consider this for inclusion.
