Not sure why this was initially rejected. It sounds reasonable to have it now as there are (and will be HWE kernels with the intel_pstate drive).

SRU justification:

Impact: When using HWE kernels in Trusty one can be using the intel_pstate driver which will result in no other power saving governor than powersave available. Given the choices (or lack of them) it is better for power usage to fall back to that instead of keeping the performance governor active.

Fix: Apply the same change we have for Utopic and add the powersave governor as the last option to check and activate.

Testcase: See reproducer in description.
