The new implementation of kunit_test_suite() for modules no longer conflicts with module_init, so can now be used by the thunderbolt tests.
Also update the Kconfig entry to enable the test when KUNIT_ALL_TESTS is enabled.
This means that kunit_tool can now successfully run and parse the test results with, for example: ./tools/testing/kunit/kunit.py run --arch=x86_64 \ --kconfig_add CONFIG_PCI=y --kconfig_add CONFIG_USB4=y \ 'thunderbolt'

Changes since v2: https://lore.kernel.org/linux-kselftest/20220621085345.603820-4-davidgow@goo... - Don't permit USB4_KUNIT_TESTS to be enabled when USB4=y and KUNIT=m i.e., add a dependency on (USB4=m || KUNIT=y) This would result in undefined kunit symbols being used, otherwise. - Add Daniel's Acked-by
Changes since v1: https://lore.kernel.org/linux-kselftest/20220618090310.1174932-4-davidgow@go... - Actually include the Kconfig changes, which were mistakenly added to the next patch in the series in v1. - Add Acked-by tag from Mika Westerberg
