No functional changes from v5. Just comment and commit message changes based on
review comments. Changelogs in patches.

Description from a previous version's cover letter:

A little bit of preparatory work to get ready for MPAM counter
assignment. Resctrl gained support last year for counter assignment for AMD
machines supporting ABMC. Tighten a few things up, that weren't needed for
AMD, so that the MPAM driver can emulate ABMC and hence support counter
assignment.

Based on v7.1-rc2
