* Add support for em(4) interfaces found on intel EP80579 SoC. The MAC part isdms2009-11-251-0/+78
basicly 82545, but the PHY's are separated form the chip and they are accessed through a special PCI device called GCU which has the MDIO interface. Since there is no direct relationship between MAC and PHY, so for the moment they are assigned to each other the way its done on Axiomtek NA-200, that was danted to us by them. This also adds a device driver for the GCU. tested by me on Axiomtek board reviewed by claudio@, kettenis@, deraadt@ 'commit that as is' deraadt@
