[flashrom] [PATCH] Add support for Intel 82599 10G NICs

[Ed Swierk]

The Intel 82599 series of 10G Ethernet controllers has a bit-banged SPI
interface that's register-compatible with the one in the 1G controllers,
except the register addresses are shifted up by 0x10000.  See
http://www.intel.com/content/www/us/en/ethernet-controllers/82599-10-gbe-controller-datasheet.html.

I tested this with a board that has the 0x10fc device and a Micron M25P40
SPI flash chip.  I filled in device IDs for other 82599 devices per
https://www-ssl.intel.com/content/www/us/en/ethernet-controllers/82599-10-gbe-controller-spec-update.html
and lifted the name strings from the PCI SIG device ID registry.
