[SPARC64]: Add LDOM virtual channel driver and VIO device layer.
Virtual devices on Sun Logical Domains are built on top of a virtual channel framework. This, with help of hypervisor interfaces, provides a link layer protocol with basic handshaking over which virtual device clients and servers communicate. Built on top of this is a VIO device protocol which has it's own handshaking and message types. At this layer attributes are exchanged (disk size, network device addresses, etc.) descriptor rings are registered, and data transfers are triggers and replied to. Signed-off-by: David S. Miller <davem@davemloft.net>
