[Skiboot] [PATCH v2 0/3] Support PCI Virtual Device

[Gavin Shan]

The patches support PCI virtual device. The NVLinks are presented to Linux
kernel via PCI virtual (emulated) device. As we're going to support NVLink2
pretty soon, we need support PCI virtual device in common layer so that it
can be shared by NVLINK1/2.

Changelog
=========
v1 -> v2:
   * Rebased to master branch per requested by Stewart. No code changes
     since v1. The last commit is f102c9d19078 ("Merge skiboot-5.3.1
     release notes").
   * Had quick test on Garrison1 and no obvious issues found.
