[PATCH] lib: sort: make it explicitly non-modular

[Paul Gortmaker]

The Makefile currently controlling compilation of this code is:

     lib/Kconfig.debug:config TEST_SORT
     lib/Kconfig.debug:      bool "Array-based sort test"

and...

     lib/Makefile:obj-y += bcd.o div64.o sort.o [...]

...meaning that it currently is not being built as a module by anyone.

Lets remove the couple traces of modular infrastructure use, so that
when reading the code there is no doubt it is builtin-only.

Since module_init translates to device_initcall in the non-modular
case, the init ordering becomes slightly earlier when we change it
to use subsys_initcall as done here.  However, since it is a self
contained test, this shouldn't be an issue and subsys_initcall
seems like a better fit for this particular case.

We also delete the MODULE_LICENSE tag since that information is now
contained at the top of the file in the comments.

[since this recently appeared in next via the akpm feed, I'm
 fine with this commit being squashed into the original. ]
