Input: atkbd - Samsung NC10 key repeat fix

commit 4200844bd9dc511088258437d564a187f0ffc94e upstream.

This patch fixes the key repeat issue with the Fn+F? keys on the new
Samsung NC10 Netbook, so that the keys can be defined and used within
ACPID correctly, otherwise the keys repeat indefinately.

This solves part of http://bugzilla.kernel.org/show_bug.cgi?id=12021
