[Impact]

AMD MP2 controller not correctly enabled on new processors and thus the
associated sensors.

  pcie_mp2_amd: probe of 0000:c4:00.7 failed with error -12

[Fix]

6 upstream commits from v6.9-rc1. 2 already in linux-6.8 stable.

[Test Case]

The MP2 shall ben enabled correctly with:

  c4:00.7 MP2 I2C controller: Advanced Micro Devices, Inc. [AMD] Device 15e6

[Where problems could occur]

No. This enables MP2 on new processor families with backward support.

[Other Info]

While this is on v6.9-rc1 only, Noble and oem-6.8 will be nominated for fix.
