docs: Remove unused weirdly-named cross-reference targets

In the doc sources, we have a few cross-reference targets with odd names "pcsys_005fxyz". These are the legacy of the semi-automated conversion of the old info docs to rST (the '005f' is because ASCII 0x5f is '_' and the old info link names had underscores in them). Remove the targets which nothing links to, and rename the two targets which are used to something a bit more descriptive.

 However, you may also need to perform additional steps to activate SR-IOV
