Subject: [PATCH] tty/metag_da: Avoid module_init/module_exit

The metag_da TTY driver can't get built as a module at the moment, but
it still uses module_init() and module_exit(). Those macros are moving
to module.h which isn't included by metag_da.c, which will result in the
following build warnings (remarkably no build errors) and an apparent
failure to boot as the TTY driver won't be loaded.

drivers/tty/metag_da.c:660: warning: type defaults to âintâ in declaration of âmodule_initâ

drivers/tty/metag_da.c:670 : warning: passing argument 4 of âchancallâ discards qualifiers from pointer target type

Instead of just adding the module.h include, now would be a good time to
remove the use of these macros, replacing the module_init with
device_initcall, and removing the exit function altogether since it
isn't needed. If module support is added later the code can always be
resurrected.

Yes, that does the trick.
