[Impact]

Missing AMD-PMF support for AMD Strix platforms.

[Fix]

A few commits from v6.9-rc1.

[Test Case]

And feature enabled message should appear in dmesg:

  amd-pmf AMDI0103:00: registered PMF device successfully

Access via sysfs:

  root at test:/sys/devices/platform/AMDI0103:00# cat cnqf_enable
  on

[Where problems could occur]

PMF once caused cpufreq locks or other unexpected behaviors in the past
and may take additional fix to address.

[Other Info]

While this is in v6.9-rc-1 now, Noble and OEM-6.8 will be nominated for
fix.
