Title:
  Add support for AMD PMF Cool and Quiet Framework (CnQF)

Bug description:
  [SRU Justification]

  [Impact]

  Missing AMD CnQF that will dynamically adjust performance and power
  consumption based upon OEM specified metrics on supported systems.

  [Fix]

  Three commits from linux-next to be backported to oem-6.0 and above.

  [Test Case]

  To enable this in AMD Phoenix CRB:

    BIOS: AMD PBS > AMD PMF Settings, enable function 11/12 & flag=1

  And feature enabled message should appear in dmesg:

    [ 3.203628] amd-pmf AMDI0102:00: registered PMF device successfully

  Access via sysfs:

    root@test:/sys/devices/platform/AMDI0102:00# cat cnqf_enable
    on

  [Where problems could occur]

  This is a new feature and will probably receive some more fixes in the
  future. So far we have little, in both kernel and userspace, runtime and
  testing, involved.

  [Other Info]

  This series depends on AMD PMF support in bug 1987670. And since these
  patches targets v6.1 and AMD phoenix target oem-6.0, only oem-6.0 and
  unstable is nominated for fix.

  ========== original bug description ==========

  CnQF is a feature that will dynamically adjust performance and power
  consumption based upon OEM specified metrics on supported systems.

  This is targeted for 6.1.
