[SRU] [OEM-5.17] [PATCH 0/1] Fix non-working I219 ethernet after s2idle

[Kai-Heng Feng]

BugLink: https://bugs.launchpad.net/bugs/1986751

[Impact]
I219 may stop working after s2idle. The link is up but failed to get an
IP address from DHCP server.

[Fix]
Revert the workaround patch "e1000e: Fix possible HW unit hang after an
s0ix exit" so the new fix "e1000e: Enable GPT clock before sending
message to CSME" can work.

[Test]
With the patch applied, the I219 device always get ip address and all
the functionalities are working.

[Where problems could occur]
It's really hard to say since the interaction between I219 and Intel ME
is very arcane. The good thing is that the fix is limited to e1000e.
