This patch does a few things:
 - Adds node_guid and node_desc fields to struct ib_device
 - Has mthca set these fields on startup
 - Extends modify_device method to handle setting node_desc
 - Exposes node_desc in sysfs
 - Allows userspace to set node_desc by writing into sysfs file, eg.
     echo -n `hostname` >> /sys/class/infiniband/mthca0/node_desc

This should probably be combined with Sean's work to get rid of
node_guid queries in ULPs.

Comments?

Are there any objections to separating the node_guid changes and commit that portion?
