Subject: [PATCH v2 1/2] Input: atkbd - Make it possible to apply atkbd.reset via kernel quirk

atkbd.reset was only a command line parameter. Some devices might have a
known bug that can be worked around by just permanently applying this
quirk.

This patch adds the ability to do this on the kernel level for known buggy
devices.
