This patchset fixes various runtime pm issues while testing pm runtime
on NGD slimbus controller.

During testing it was found that pm refcount was going negative and sometime
transactions are timeout after suspend resume.

These 4 patches fixes those issues and now NGD enters in supend state
and resumes properly without any data timeouts.

Thanks,
srini
