input: touchboost: remove keypad filter, it seems that some idiot decided to bundle Bluetooth disconnect event through the keypad filter so users were having kernel_panics in that scenario. Also no need to call cpufreq_driver_target because interactive's speedtask thread will push do it for us in the next timer_rate. Since timer_rate is 30ms by default we adjust the minimum frequency for 40ms up to input_boost_freq, then the governor will catch up.
