Add new programmer for SPI EEPROMs attached to Intel 82580 NICs

This patch lets you read and write the EEPROM on 82580-based gigabit NIC
cards. So far it has been tested on copper NICs only, but other variants
employing this controller should work too.
It is a nice substitution for the official eeupdate tool.

Speed is quite decent: less than 4 seconds for erases or writes of 32 kB.

Corresponding to flashrom svn r1832.
