Timothy Pearson 83abd81c8a cpu/amd: Add CC6 support
This patch adds CC6 power save support to the AMD Family 15h
support code.  As CC6 is a complex power saving state that
relies heavily on CPU, northbridge, and southbridge cooperation,
this patch alters significant amounts of code throughout the
tree simultaneously.

Allowing the CPU to enter CC6 allows the second level of turbo
boost to be reached, and also provides significant power savings
when the system is idle due to the complete core shutdown.
