With the introduccion of the new keyboard backlight
implementation, the *_timeout_store function is
broken, as it only supports the first kbd_type.
This patch adapt such function for the new kbd_type,
as well as convert from using sscanf to kstrtoint.

Changes since v1:
- Check for timeout values depending on kbd_type
- Removed some misleading comments
Note: I'll be out of town until the next weekend,
in case something else needs to be changed, I'll
catch up whenever I'm back.

Functional changes look good to me, thank you.
I've made a couple minor formatting corrections in the interest of time. In
the future, please check your patches with checkpatch.pl and consider using a
spell checker in your $EDITOR for commit messages. Using git am to apply your
own patches would also have caught the whitespace error.

Queued to testing, I'll push to for-next tomorrow(ish), which should give us
enough time to make 3.18 since Linus pushed out the merge window a bit.
