Add new programmer for SPI EEPROMs attached to Intel 82580 NICs

Browse Source 
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.

.BR "nicintel_eeprom " programmer
This is the first programmer module in flashrom that does not provide access to NOR flash chips but EEPROMs
mounted on gigabit Ethernet cards based on Intel's 82580 NIC. Because EEPROMs normally do not announce their
size nor allow to be identified, the controller relies on correct size values written to predefined addresses
within the chip. Flashrom follows this scheme but assumes the minimum size of 16 kB (128 kb) if an unprogrammed
EEPROM/card is detected. Intel specifies following EEPROMs to be compatible: Atmel AT25128, AT25256, Micron (ST)
M95128, M95256 and OnSemi (Catalyst) CAT25CS128.
