Aura perf. profile workaround

Browse source 
Explicitly sets the performance profile for Aura on keyboard init.
This has the effect of setting the state (previously not done by
firmware) to the relevant ACPI object. After this it should
restore the performance profile correctly on its own on power supply
change.
