IB/core: Allow device-specific per-port sysfs files
Add a new parameter to ib_register_device() so that low-level device
drivers can pass in a pointer to a callback function that will be
called for each port that is registered in sysfs. This allows
low-level device drivers to create files in
/sys/class/infiniband/<hca>/ports/<N>/
without having to poke through the internals of the RDMA sysfs handling.
There is no need for an unregister function since the kobject
reference will go to zero when ib_unregister_device() is called.
