drm/i915: keep max backlight internal to intel_panel.c
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.
