Ulf reported an issue[1] with fw_devlink. This series tries to fix that
issue.

I replicated a similar set up on my end and I confirmed:
- A simple-bus only device is probed.
- Another device listing simple-bus as a 2nd compatible string isn't
  probed.

Ulf, mind testing this?

v1->v2:
- Switched to probing the simple-bus device instead of marking it as
  NEVER_PROBES.

v2->v3:
- Moved all the code into the simple-pm-bus driver
- Addressed Ulf's comment about the remove() code missing a check.

Thanks,
Saravana
