[Impact]
e1000e on TGP PCH encounters a network speed issue that rx speed is below
1MB/s

[Fix]
Intel provides 2 patches to fix this

[Test]
Verified by our Dell and Lenovo platforms and the bug reporter.

[Where problems could occur]
The fix only applies to e1000e with TGP PCH, and add a flag
"E1000_FFLT_DBG_DONT_GATE_WAKE_DMA_CLK". The impact should be minimized
and should not lead to other regressions.
