Need to get fine-grained control for FAN(TFN) Participant.

[Philip Cox]

This is a public version of the following bugs:
https://bugs.launchpad.net/bugs/1987597
https://bugs.launchpad.net/bugs/2027754

----------------

[Feature Description]
We need Fine-grained Control of TFN participant for enabling active 2 policy in Linux/chrome.

Currently, The kernel has provided __FPS table and cur__state to adjust the fan level as per _FPS table .

But there is no option to read *_FIF (Fan Information) and _FST (Fan Status).*

Once the fine-grained control is enabled, we should be able to the set the control value from 0-100 through Arg0 of _FSL (Fan Set Level).

*_FST (Fan Status)* should report current running RPM and control value of the FAN(TFN).

 please refer ACPI spec for more detail.

This bug is awaiting verification that the linux/5.15.0-85.95 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-jammy-linux' to 'verification-done-jammy-linux'. If the problem still exists, change the tag 'verification-needed-jammy-linux' to 'verification-failed-jammy-linux'.

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.
