[Fix]
Below commit fixes this issue
https://patchwork.ozlabs.org/project/intel-wired-lan/patch/20220508070905.1878172-1-sasha.neftin@intel.com/

[Test]
Verified on the target machine, and confirmed the issue is gone.

[Where problems could occur]
The impact is low, it keeps the GPT clock enabled for CSME when e1000e_pm_resume() is called. I can't see this may introduce any regression.
