e1000e: rework disable K1 at 1000Mbps for 82577/82578
This patch reworks a previous workaround (commit 7d3cabbcc) for an issue in hardware where noise on the interconnect between the MAC and PHY could be generated by a lower power mode (K1) at 1000Mbps resulting in bad packets. Disable K1 while at 1000 Mbps but keep it enabled for 10/100Mbps and when the cable is disconnected. The original version of this workaround was found to be incomplete.
