Log:
Add board enable for ABIT AV8

I disassembled the write enable and the write disable functions from
the Award BIOS image and reconstructed C code to understand for
myself what happens. For details see:
http://www.flashrom.org/pipermail/flashrom/2011-October/008033.html

I compared the download pages of both, abit AV8 and abit AV8-3rd Eye,
and the BIOS downloads are the same. So it's save to assume that this
board enable works on both versions. Tested on AV8.
