Curious for other platforms node_distance number, actually, this
assumption is right for what I saw Intel platforms. but it is not
match acpispec50.pdf:

Table 6-152 Example Relative Distances Between Proximity Domains
Proximity Domain 0 1 2 3
0 10 15 20 18
1 15 10 16 24
2 20 16 10 12
3 18 24 12 10
