cpufreq: ondemand: Replace down_differential tuner with adj_up_threshold
In order to avoid the calculation of up_threshold - down_differential every time that the frequency must be decreased, we replace the down_differential tuner with the adj_up_threshold which keeps the difference across multiple checks. Update the adj_up_threshold only when the up_theshold is also updated.
