x86: uv: update XPC to handle updated BIOS interface
The UV BIOS has moved the location of some of their pointers to the
"partition reserved page" from memory into a uv hub MMR. The GRU does not
support bcopy operations from MMR space so we need to special case the MMR
addresses using VLOAD operations.
Additionally, the BIOS call for registering a message queue watchlist has
removed the 'blade' value and eliminated the structure that was being
passed in. This is also reflected in this patch.
