[PATCH 10/19] pmdomain: add stub definition for dev_pm_domain_detach

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

Detaching a power domain frees the virtual device if any was allocated
and may power down the domain if no users remain.

We don't do reference counting for users and don't mind power domains
remaining enables as the kernel will enable unused power domains on its
own anyway. Thus implement dev_pm_domain_detach() as empty stub.
