> Add Nvidia nForce MCP61/MCP65/MCP67/MCP78S/MCP73/MCP79 SPI flashing support.

JFTR: On the motherboard which I originally reported ("NVIDIA MCP65,
MSI MS-7369  "K9N Neo V2"  v1.0  (2007)"), reading and verifying the
BIOS was successful using r1182, which is HEAD as of today.


# flashrom -Vr /tmp/bios
flashrom v0.9.2-r1182 on Linux (x86_64), built with libpci 3.1.7, GCC 4.5.0 20100604 [gcc-4_5-branch revision 160292], little endian
flashrom is free software, get the source code at http://www.flashrom.org

Calibrating delay loop... OS timer resolution is 1 usecs, 1378M loops per second, 10 myus = 11 us, 100 myus = 100 us, 1000 myus = 996 us, 10000 myus = 10214 us, 4 myus = 4 us, OK.
