platform/x86: dell-wmi: Set correct keycode for Fn + left arrow

Fn + left arrow hotkey combination is used for enabling/disabling automatic
display brightness based on integrated ALS sensor. For this purpose there
is standard Linux key KEY_BRIGHTNESS_AUTO so use it instead of KEY_UNKNOWN.

Tested on Dell Lattitude E6500.
