Subject: cpufreq: interactive: always limit initial speed bump to hispeed
X-Git-Tag: firefly_0821_release~4090^2~671

cpufreq: interactive: always limit initial speed bump to hispeed

First bump speed up to hispeed_freq whenever the current speed is below
hispeed_freq, instead of only when the current speed is the minimum speed.
The previous code made it too difficult to use hispeed_freq as a common
intermediate speed on systems that frequently run at speeds between
minimum and hispeed_freq.
