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.
