[PATCH] e1000: Added hardware support for PCI express, 82546GB, and 82571 Fiber

Added 82571 fiber to WOL fix for dual port adapters.
Added support for 82546GB (Quad Copper).
Added PCIe typedef for x2, igp cable length 115, and extended TX CTRL registers.
Added parity error detection and PCIe CTRL registers.
Added EEPROM config registers.
