[PATCH 11/19] pmdomain: add stub definition for pm_runtime_put_genpd

[Ahmad Fatoum]

Putting a runtime PM reference will send a device into runtime suspend
once no users remain.

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