Commit 3c7bf5af21960 ("e1000e: Introduce private flag to disable K1")
disabled K1 by default on Meteor Lake and newer systems due to packet
loss observed on various platforms. However, disabling K1 caused an
increase in power consumption due to blocking PC10 state.
To mitigate this, reconfigure the PLL clock gate value so that K1 can
remain enabled without incurring the additional power consumption.
