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.
