Input: atkbd - add a quirk for OQO 01+ multimedia keys
OQO 01+ multimedia keys produce 6x on press, e0 6x upon release.
As a result, Linux thinks that another key has been pressed (or is
repeating), when it is actually a release of the same key. Mangle the
release scancode when running on OQO so that driver recognizes it as
such.
Since the device does not have external PS/2 ports mangling is safe
since there is no chance that an external keyboard is connected.
