Fix sub-optimal I210 network speed

[Kai-Heng Feng]

[Impact]
I210 may not reach maximum speed on Intel Alder Lake platforms.

[Fix]
Following the datasheet to ensure I210 is not in idle state when CPU is
using PCIe link to perform TX.

[Test]
With the fix applied, the I210 TX/RX speed can reach ~94x MBps.

[Where problems could occur]
Since this changes how hardware idles, it can slightly increase power
consumption.
