The kunit_test_suite() macro is no-longer incompatible with module_add,
so its use can be reinstated.

Since this fixes parsing with builtins and kunit_tool, also enable the
test by default when KUNIT_ALL_TESTS is enabled.

The test can now be run via kunit_tool with:
	./tools/testing/kunit/kunit.py run --arch=x86_64 \
	--kconfig_add CONFIG_OF=y --kconfig_add CONFIG_OF_ADDRESS=y \
	--kconfig_add CONFIG_MMC=y --kconfig_add CONFIG_MMC_SDHCI=y \
	--kconfig_add CONFIG_MMC_SDHCI_PLTFM=y \
	--kconfig_add CONFIG_MMC_SDHCI_OF_ASPEED=y \
	'sdhci-of-aspeed'

(It may be worth adding a .kunitconfig at some point, as there are
enough dependencies to make that command scarily long.)

Minor, optional suggestion below.

This goto was added in 4af307f57426 ("mmc: sdhci-of-aspeed: Fix
kunit-related build error") to allow for this extra call to
aspeed_sdc_tests_init().

This could now be reverted back to what is
        rc = platform_driver_register(&aspeed_sdc_driver);
        if (rc < 0)
               platform_driver_unregister(&aspeed_sdhci_driver);

        return rc;

but let's see what the maintainers think.

I don't have a strong opinion on this, feel free to pick any of the options.
