<pre>Currently, powertop displays RC6p and RC6pp on all platforms, even though
current hardware just has one unified RC6 state. This generates support
questions ("why isn't my system getting into a deeper sleep state?").
The kernel driver should not export rc6p_residency_ms or rc6pp_residency_ms at
all on hardware platforms that don't have those distinct states. We can then
teach powertop to only display the states for which _residency_ms files exist.
(I've confirmed that existing versions of powertop will simply display 0
residency if the files don't exist, as though they existed and contained 0.)</pre>
