sysfs: Add support for permanently empty directories to serve as mount points.
commit 87d2846fcf88113fae2341da1ca9a71f0d916f2c upstream.
Add two functions sysfs_create_mount_point and
sysfs_remove_mount_point that hang a permanently empty directory off
of a kobject or remove a permanently emptpy directory hanging from a
kobject. Export these new functions so modular filesystems can use
them.
