x86, UV: Update node controller MMRs
A new version of the SGI UV hub node controller is being
developed. A few of the MMRs (control registers) that exist on
the current hub no longer exist on the new hub. Fortunately,
there are alternate MMRs that are are functionally equivalent
and that exist on both hubs.
This patch changes the UV code to use MMRs that exist in BOTH
versions of the hub node controller.
