Series phy: core: Re-work runtime PM deployment and fix an issue | expand

Commit Message

Ulf Hansson Dec. 19, 2017, 9:22 p.m. UTC 
The phy core already deploys runtime PM management, so there seems to be no
reason for having a separate option of controlling runtime PM for phys via
the phy runtime PM APIs.

Moreover, since previous changes moved the runtime PM reference counting
onto the parent provider device, which also avoid to enabled runtime PM for
the phy child device, the APIs becomes NOOP. Therefore, let's remove them
altogether.
