cpu/amd/fam10h-15h: Fix link type detection and XCS buffer count setup

The existing code did not properly detect various link attributes
on Family 10h/15h processors.  With the addition of new HT3- and
IOMMU-specific code, proper detection has become critical to avoid
system deadlocks.

Fix and streamline link attribute detection.
