Dan Williams 88f3b62ac1 isci: move remote_device handling out of the core
Now that the core/lldd remote_device data structures are nominally unified
merge the corresponding sources into the top-level directory.  Also move the
remote_node_context infrastructure which has no analog at the lldd level.
