Driver core changes for 5.14-rc1

Here is the small set of driver core and debugfs updates for 5.14-rc1.

Included in here are:
	- debugfs api cleanups (touched some drivers)
	- devres updates
	- tiny driver core updates and tweaks

Nothing major in here at all, and all have been in linux-next for a
while with no reported issues.
