drivers: base: Add basic devm tests for root devices The root devices show some odd behaviours compared to regular "bus" devices that have been probed through the usual mechanism, so let's create kunit tests to exercise those paths and odd cases. It's not clear whether root devices are even allowed to use device managed resources, but the fact that it works in some cases but not others like shown in that test suite shouldn't happen either way: we want to make it consistent and documented. These tests will (after the following patches) ensure that consistency and effectively document that it's allowed. If it ever turns out to be a bad idea, we can always roll back and modify the tests then.

drivers: base: test: Add missing MODULE_* macros to root device tests Commit 06188bc80ccb ("drivers: base: Add basic devm tests for root devices") introduced a new set of tests for root devices that could be compiled as a module, but didn't have the usual module macros. Make sure they're there.
