Given this is a new configuration, there are affects on APIC, CEDT
and DSDT, but the key elements are in SRAT (plus related data in
HMAT). The configuration has node to exercise many different combinations.
0) CPUs + Memory
1) GI only
2) GP only
3) CPUS only
4) Memory only
5) CPUs + HP memory
GI node, GP Node, Memory only node, hotplug memory
only node, latency and bandwidth such that in Linux Access0
(any initiator) and Access1 (CPU initiators only) given different
answers. Following cropped to remove details of each entry.

Note the zeros represent entries where the target node has no
memory. These could be surpressed but it isn't 'wrong' to provide
them and it is (probably) permissible under ACPI to hotplug memory
into these nodes later.
