tuna: Add Power HAL
* Add Power HAL for Tuna.
* Update cpufreq interactive governor params:
min_sample_time = 100ms to cover bursts of graphics load
go_hispeed_load = 40% to handle graphics loads
* Move screen off maximum frequency to generic cpufreq
scaling_max_freq interface, set when turning screen on/off.
* Move cpufreq init from init.rc to Power HAL.
