[SPARC64]: Add basic infrastructure for MD add/remove notification.
And add dummy handlers for the VIO device layer. These will be filled in with real code after the vdc, vnet, and ds drivers are reworked to have simpler dependencies on the VIO device tree. Signed-off-by: David S. Miller <davem@davemloft.net>
