Introduce a new kselftest to detect devices that were declared in the Devicetree, and are expected to be probed by a driver, but weren't.
The test uses two lists: a list of compatibles that can match a Devicetree device to a driver, and a list of compatibles that should be ignored. The first is automatically generated by the dt-extract-compatibles script, and is run as part of building this test. The list of compatibles to ignore is a hand-crafted list to capture the few exceptions of compatibles that are expected to match a driver but not be bound to it.

Hi Nicolas,
Currently when building kselftest against next-master and mainline-master the below build error is observed. A bisect (full log below) identified this patch as introducing the failure.
Full log from a failure:

May be due to, A loop of symlinks that are pointing to self / same files ?

Here is the log showing selftests/dt build pass for arm64 build from Linux next master branch.
