e1000 net driver update 3/4: 

* Added four new device IDs: 82545EM_COPPER, 82545EM_FIBER,
82546EB_COPPER, 82546EB_FIBER.
* Added a couple magic number definitions for DMA addressable bits.
* Added Power Management Suspend/Resume support.
* Added reboot notifier registration to setup WOL when shutting down.
