[SRU][Q][PATCH 0/9] Enable PMF on AMD HPT/STX/KRK

[AceLan Kao]

From: "Chia-Lin Kao (AceLan)" <acelan.kao at canonical.com>

BugLink: https://bugs.launchpad.net/bugs/2125022

[Impact]
It is for basic AMD HPT/STX/KRK function. Current PMF driver missing two features:
1. For the thermal policy input, the AMD Fusion Sensor Hub could not pass the data to PMF driver.
2. PMF driver could not parse the thermal policy binary which is stored in the BIOS.

[Fix]
Need this series of patches which is included in v6.18-rc1

[Test]
PMF driver is loaded and function works properly on AMD platforms.

[Where problems could occur]
It's hard to evaluate the problems those patches may occur. Most of them
are withing amd/pmf, so it only impact the amd pmf functionailties.
