asus-laptop: code movement
The asus-laptop driver implements a number of interfaces like the backlight class driver. This change makes it easier to examine the implementation of one interface at at a time, without having to search through the file to find init() and exit() functions etc. Signed-off-by: Corentin Chary <corentincj@iksaif.net>
