keymap: handle atkbd force_release quirk

Some laptop keyboards don't generate release events
for some hotkeys.  Since linux-2.6.32 the list of scancodes
for which to enable the force_release quirk can be set
via sysfs.
Apply this to Samsung N130.

+# Set model specific atkbd force_release quirk
+#
+# Several laptops have hotkeys which don't generate release events,
+# which can cause problems with software key repeat.
+# The atkbd driver has a quirk handler for generating synthetic
+# release events, which can be configured via sysfs since 2.6.32.
+# Simply add a file with a list of scancodes for your laptop model
+# in /lib/udev/keymaps, and add a rule here.
+# If the hotkeys also need a keymap assignment you can copy the
+# scancodes from the keymap file, otherwise you can run
+# /lib/udev/keymap -i /dev/input/eventX
+# on a Linux vt to find out.
