nvidia southbridges: don't touch 0x78 in LPC bridge with Fam10h
Based on the observations that AMD Fam10h with both Nvidia CK804 (Asus
KFSN4-DRE) and MCP55 (Sun Ultra 40 M2) need to avoid adjusting the LPC
bridge register 0x78 (particularly the 0x7b byte) to get to ramstage:
Assume that there's something about this register that adjusting it the
way we do for K8 is something that can/should be universally avoided on
all Fam10h systems with these chipsets.
