Infiniband: make ipath driver use default driver groups.

Make the ipath driver use the new driver functions so that it does not
touch the sysfs portion of the driver structure.

We also remove the redundant symlink from the device back to the driver,
as it is already in the sysfs tree.  Any userspace tools should be using
the standard symlink, not some driver specific one.
