[Skiboot] [PATCH 0/6] OpenCAPI support for Witherspoon

[Andrew Donnellan]

This series implements OpenCAPI support for Witherspoon.

Patch 1 is a fixup to the OCC GPU presence detection.

Patches 2-4 are restructuring of the NPU code in preparation for
platforms that support both NVLink and OpenCAPI.

Patch 5 is a fixup to OpenCAPI I2C reset and presence detection.

Patch 6 adds Witherspoon-specific platform support, including the
Witherspoon-specific device presence and type detection.

I'm still testing this on a few platforms to try and avoid regressions.
Reza/Alistair it would be great if you could test on your NVLink machines,
my test machine does have a GPU in it which still seems to work.
