  From: Arnd Bergmann <arnd@arndb.de>

In configurations with CONFIG_KUNIT=m, builting the unit test
into the kernel causes a link failure:

arm-linux-gnueabi-ld: drivers/gpu/drm/vc4/tests/vc4_mock.o: in function `__build_mock':
vc4_mock.c:(.text+0x6e): undefined reference to `kunit_do_failed_assertion'
arm-linux-gnueabi-ld: vc4_mock.c:(.text+0x9c): undefined reference to `kunit_do_failed_assertion'
arm-linux-gnueabi-ld: vc4_mock.c:(.text+0x100): undefined reference to `kunit_ptr_not_err_assert_format'
...

Allow this to be a loadable module as well to have Kconfig
sort out the dependencies correctly.

Applied to drm/drm-misc (drm-misc-next-fixes).
