We also currently don't have a devlink between it and the actual reset consumer. Suppress sysfs bind attributes so that user-space can't unbind the device because - as of now - it will cause a use-after-free splat from any user that puts the reset control handle.

The driver is expected to be used by reset core framework for ad-hoc reset controllers.
