e1000e: add support for 82577/82578 GbE LOM parts
This patch provides support for the next generation Intel desktop and mobile gigabit ethernet LOM adapters. These adapters are the follow-on parts to the LOMs tied to the prior ICH chipsets and are comprised of a MAC in the PCH chipset and an external PHY (82577 for mobile and 82578 for desktop versions). New features consist of PHY wakeup to save power by completely turning off the MAC while in Sx state, and 4K jumbo frames.
