[coreboot] Support for Asus M2N-SLI Deluxe

[Michael Cassaniti]

Hi,
Answering the following questions from the FAQ, I have the following:

Board Vendor: Asus
Board Product Name: M2N-SLI Deluxe
CPU Model: AMD Athlon 64FX, Socket AM2
Northbridge: Nvidia nForce 570 SLI
Southbridge: Nvidia MCP55
Link to specifications:

Attached are the outputs of lspci, superiotool and flashrom.

I noticed that a similar board (Asus M2N-E) is supported. I was hoping that
porting to this board would not require major rework.

Regards,
