This follows up commit ebd09577be6c ("lib/test: convert
lib/test_list_sort.c to use KUnit").
Converting this test to KUnit makes the test a bit shorter, standardizes
how it reports pass/fail, and adds an easier way to run the test [1].
Like ebd09577be6c, this leaves the file and Kconfig option name the same,
but slightly changes their dependencies (needs CONFIG_KUNIT).
[1] Can be run via
$ ./tools/testing/kunit/kunit.py run --kunitconfig /dev/stdin <<EOF
CONFIG_KUNIT=y
CONFIG_TEST_SORT=y
EOF

[11:30:30] Testing complete. 1 tests run. 0 failed. 0 crashed. 0 skipped.
[11:30:30] Elapsed time: 37.032s total, 0.001s configuring, 34.090s building, 0.000s running
Note: this is the time it took after a `make mrproper`.
With an incremental rebuild, this looks more like:
[11:38:58] Elapsed time: 6.444s total, 0.001s configuring, 3.416s building, 0.000s running
Since the test has no dependencies, it can also be run (with some other
tests) with just:
$ ./tools/testing/kunit/kunit.py run

test_sort.c performs array-based and linked list sort test. Code allows
to compile either as a loadable modules or builtin into the kernel.
Current code is not allow to unload the test_sort.ko module after
successful completion.
This patch adds support to unload the "test_sort.ko" module by adding
module_exit support.
Previous patch was implemented auto unload support by returning -EAGAIN
from module_init() function on successful case, but this approach is not
ideal.
The auto-unload might seem like a nice optimization, but it encourages
inconsistent behaviour. And behaviour that is different from all other
normal modules.

Patch series "lib: add module support to sort tests".
This patch series allows to compile the array-based and linked list sort
test code either to loadable modules, or builtin into the kernel.
It's very valuable to have modular tests, so you can run them just by
insmodding the test modules, instead of needing a separate kernel that
runs them at boot.
This patch (of 3):
This reverts commit 8893f519330bb073a49c5b4676fce4be6f1be15d.

The Kconfig currently controlling compilation of this code is:
lib/Kconfig.debug:config TEST_SORT
lib/Kconfig.debug: bool "Array-based sort test"
...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.

Along with the addition made to Kconfig.debug, the prior existing but
permanently disabled test function has been slightly refactored.
Patch has been tested using QEMU 2.1.2 with a .config obtained through
'make defconfig' (x86_64) and manually enabling the option.
