northbridge/amd/amdmct: Fix broken AMD K10 DDR3 memory initalization
The native AMD DDR3 memory initialization code was riddled with
numerous errors and was missing critical configuration code segments;
this made it so that DDR3 memory did not function on most AMD boards.
This patch corrects enough of the DDR3 initialization such that
UDIMMs can be used on most channels of G34 Opteron boards. Further
work is needed to fix the broken RDIMM code and remaining UDIMM issues.
