char: remove unnecessary module_init/exit functions

char: remove unnecessary module_init/exit functions

Two char drivers have unnecessary module_init and module_exit functions
that are empty or just print a message. Remove them. Note that if a
module_init function exists, a module_exit function must also exist;
otherwise, the module cannot be unloaded.
