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 from a script that parses the kernel source using Coccinelle, and will be run as part of building this test, therefore Coccinelle is a build-time dependency for 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.
This doesn't appear to produce KTAP output which is going to make it less useful for generic kselftest runners.
