[coreboot] Asus M2A-VM status

[Carl-Daniel Hailfinger]

The Asus M2A-VM is working pretty well, but there is still lots of stuff
to fix before the board is production ready.

I added some info to the wiki page:
http://www.coreboot.org/ASUS_M2A-VM#Other_issues

Help to fix the remaining issues is appreciated.

Once the MMCONFIG bug has been fixed, I plan to commit the M2A-VM as new
target to the svn tree.

Regards,
Carl-Daniel
