[RFC PATCH v2 08/14] device_cgroup: Hide devcgroup functionality completely in lsm

[Michael Weiß]

Now since all users of devcgroup_check_permission() have been
removed, all device cgroup related functionality is covered by
security hooks. Thus, move the public device_cgroup.h header
into the subfolder of the lsm module.
