Bug description:
[Impact]
During AMD Genoa development, the datacenter team identified
performance regressions that were root caused in the amd-pstate
driver. A first round of fixes already landed upstream (v6.1-rc7) in
the amd-pstate driver, and should be backported to all the affected
kernels.
[Fix]
Backport the upstream amd-pstate fixes:

pm/20221117073541.3350600-1-perry.y...@amd.com/T/#m4616d857ca472937d1e1d31131ddc3261fa17b2a
[Regression potential]
Clean cherry-picks of already upstream (v6.1-rc7) fixes, impact a
single driver (amd-pstate) and the new mode (passive) is disabled by
default.
