x86/UV: Add GRU distributed mode mappings

Browse source

GRU hardware will support an optional distributed mode that will
allow  per-node address mapping of local GRU space, as opposed
to mapping all GRU hardware to the same contiguous high space.

If GRU distributed mode is selected, setup per-node page table
mappings.
