[PATCH V2 05/11] PM / Domains: Allow a better error handling of dev_pm_domain_attach()

The callers of dev_pm_domain_attach() currently checks the returned error code for -EPROBE_DEFER and needs to ignore other error codes. This is an unnecessary limitation, which also leads to a rather strange behaviour in the error path. Address this limitation, by changing the return codes from
