asus-laptop: change light sens default values.

The light sensor disable brightness key and
/sys/class/backlight/ control. There was a lot of report
from users who didn't understand why they couldn't change their
brightness, including:

https://bugs.launchpad.net/bugs/222171
https://bugzilla.novell.com/show_bug.cgi?id=514747
http://bugzilla.kernel.org/show_bug.cgi?id=13671
http://bugzilla.kernel.org/show_bug.cgi?id=14432



Now the light sensor is disabled, and if the user want to enable
it, the level should be ok.

The funny thing is that comments where ok, not code.
