In preparation of adding locking to backlight, make max backlight value (the modulation frequency the PWM duty cycle value must not exceed) internal to intel_panel.c. Have intel_panel_set_backlight() accept a caller defined range for level, and scale input to max backlight value internally. Clean up intel_panel_get_max_backlight() and usage internally.
