[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.
