Add AMD Agesa and AMD CIMx SB800 code. Patch 1 of 8.
This code currently generates many warnings that are functionally benign. These are being addressed, but the wheels of bureaucracy turn slowly. This drop supports AMD cpu families 10h and 14h. Only Family 14h is used as an example in this set of patches. Other cpu families are supported by the infrastructure, but their specific support is not included herein. This patch is functionally independent of the other patches in this set.
