[coreboot] [Patch] Flashrom: Add nforce2 chipset enable.

[Luc Verhaegen]

Since no-one seems to have solid information as to the origins of 
the supposedly known brokenness of flashrom on the Asus A7N8X-E, i 
attach here a patch to add nforce2 support, which will hopefully fix 
this board.

Attached as well is some lspci info i managed to pluck off the interweb.
No subsystem ids though, but a board specific enable does not seem 
necessary for this board.
