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.

+ * @file
+ *
+ * HyperTransport features and sequence implementation.
+ *
+ * Implements the external AmdHtInitialize entry point.
+ * Contains routines for directing the sequence of available features.
+ * Mostly, but not exclusively, AGESA_TESTPOINT invocations should be
+ * contained in this file, and not in the feature code.
+ *
+ * From a build option perspective, it may be that a few lines could be removed
+ * from compilation in this file for certain options.  It is considered that
+ * the code savings from this are too small to be of concern and this file
+ * should not have any explicit build option implementation.
