[Castle Peak]: pull in CPPC fixes

[Mario Limonciello]

Recently a CPPC fix was accepted for fixing CPPC on many AMD platforms.

https://github.com/torvalds/linux/commit/3743d55b289c203d8f77b7cd47c24926b9d186ae

It's CC'ed to stable, so it will eventually flow in, but to give best performance on customer systems, can you please pull this into all sustaining OEM trees?

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-focal' to 'verification-done-focal'. If the problem still exists, change the tag 'verification-needed-focal' to 'verification-failed-focal'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
