Driver core changes for 5.16-rc1

Here is the big set of driver core changes for 5.16-rc1.

All of these have been in linux-next for a while now with no reported
problems.

Included in here are:
- big update and cleanup of the sysfs abi documentation files
and scripts from Mauro. We are almost at the place where we
can properly check that the running kernel's sysfs abi is
documented fully.
- firmware loader updates
- dyndbg updates
- kernfs cleanups and fixes from Christoph
- device property updates
- component fix
- other minor driver core cleanups and fixes
