Input: atkbd - restore resetting LED state at startup
Fix breakage caused by commit 9605fb48e1998935a5ee70c965f90ad1ac023add
While the input core indeed takes care of restoring led state and
typematic settings upon resume the driver still need to initialize
them properly when registering a new device
