[coreboot] [patch] [AMD Fam10] Fix confused RB-C2 and DA-C2

Issues:
1. I really don't know what their nicknames are (Shanghai C2 or
something).
2. About the mc_patch_01000086.h, I don't know if it is allowed to be
released.  If you really need it, please contact AMD Inc to see if it is
public.
3. My RB-C2 is Socket type AM3, which needs DDR3 support. Probably your
RB-C2 doesn't need DDR3. If it does and you really need it, please
contact AMD Inc to see if it is allowed to release DDR3 code.

I am trying to port the ddr3 feature. I will submit a full patch to
replace this one.
