[Fix]
This patch fixes the issue
https://patchwork.freedesktop.org/patch/430153/?series=89348&rev=1
It needs dependant commits on top of Hirsute base to access the stepping info to specifically disable PSR2 when stepping is B1 from A0.

[Test]
Verified on Dell TGL-H platforms.

[Where problems could occur]
It disable PSR2 on A0 and B0 TGL-H platforms, should introduce no regression.

V2: Add more dependant patches to avoid as many conflicts as possible and add explanations for all backported section.
