Attempt to get the memory and CPU NUMA node via of_numa. If that
fails, default the dummy NUMA node and map all memory and CPUs to node
0.

What happened to the patch cleaning this up in generic code?
As per 0/5 :
v11:
- Dropped cleanup patches for other architectures, they will be
submitted as a separate set after more testing.
The "cleanup patches" were not building on x86, which is a bit of a
problem. I believe I have corrected that issue, but would like to do
a little more build testing on all the other architectures that are
effected.
I probably should have supplied more detail as to my plan of attack
for these. To make review more manageable, I would like to consider
the arm64 patches separately. The parties interested in getting arm64
NUMA working can proceed without waiting for the cleanups to be fully
tested and acknowledged. I am working on testing the cleanups on each
architecture touched, and will resubmit them as a separate patch set
this week. I think splitting them like this will streamline the
process of getting to the eventual goal of having both arm64 NUMA and
the cleanups merged.
David.
