Subject: [PATCH] pmdomain: core: Move the unused cleanup to a _sync
 initcall

The unused clock cleanup uses the _sync initcall to give all users at
earlier initcalls time to probe. Do the same to avoid leaving some PDs
dangling at "on" (which actually happened on qcom!).

Fixes: 2fe71dcdfd10 ("PM / domains: Add late_initcall to disable unused PM domains")
