Today we have an issue where the NUMA nodes corresponding
to GPU's have the same affinity/distance as normal memory
nodes. Our reference-points today supports two levels
[0x4, 0x4] for normal systems and [0x4, 0x3] for Power8E
systems. This patch adds a new level [0x4, X, 0x2] and
uses node-id as at all levels for the GPU.

Add PVR detection, chip id and other misc bits for POWER9.
POWER9 changes the location of the HILE and attn enable bits in the
HID0 register, so add these definitions also.

Now that opal.h includes opal-api.h, there are a bunch of files that
include both but don't need to.

This is probably not the best collection of things in the world,
but it means that opal.h is much closer to being directly usable
by an OS.
This triggers a bunch of #include fixes throughout the tree.
