cpufreq / intel_pstate: Change to scale off of max P-state
Change to using max P-state instead of max turbo P-state. This
change resolves two issues.
On a quiet system intel_pstate can fail to respond to a load change.
On CPU SKUs that have a limited number of P-states and no turbo range
intel_pstate fails to select the highest available P-state.
This change is suitable for stable v3.9+
