[SRU] [I/Unstable/OEM-5.13/OEM-5.14] [PATCH 0/3] Fix non-working e1000e device after resume

[Kai-Heng Feng]

BugLink: https://bugs.launchpad.net/bugs/1951861

[Impact]
e1000e devices stop working after s2idle resume.

[Fix]
Revert the offending patch series, which is to bring some minor power
saving.

[Test]
Vendor did extensive tests and didn't find any regression, and the power
consumption remains the same.

[Where problems could occur]
Maybe on some system the series can save some energy, so reverting will
cause some power consumption increase.
