Ensure consistency in spmi_controller pointers between spmi_controller_remove/put and driver spmi_del_controller functions. The former requires a pointer to struct spmi_controller, while the latter passes a pointer of struct spmi_controller_dev, leading to a "Null pointer exception".

- Split into two separate patches
- add Fixes and Cc stable
You need to mark this patch more clearly as a stable backport (e.g. using a "[PATCH-stable]" prefix), and explain that the corresponding issue has already been fixed upstream by commits:
490d88ef548d ("spmi: hisi-spmi-controller: Use devm_spmi_controller_add()") ffdfbafdc4f4 ("spmi: Use devm_spmi_controller_alloc()")
but that those commits (and their dependencies) are too intrusive to backport.
