The patch below does the following cleanups for the sysfs code:
- remove the unused global function sysfs_mknod
- make some structs and functions static
Please check whether this patch is correct, or whether some of the
things I made static should be used globally in the forseeable future.

It is not used as of now, but I am not sure if there are potential
users been thought earlier.
