To maintain scalability let's add common methods to attach and detach a PM domain for a device, dev_pm_domain_attach|detach(). Typically dev_pm_domain_attach() shall be invoked from subsystem level code at the probe phase to try to attach a device to its PM domain. The reversed actions may be done a the remove phase and then by invoking dev_pm_domain_detach(). When attachment succeeds, the attach function should assign its corresponding detach function to a new ->detach() callback added in the struct dev_pm_domain.
