[v1,0/8] Support Runtime PM and host mode by Tegra ChipIdea USB driver

Message

This series implements Runtime PM support for the Tegra ChipIdea USB driver.
It also squashes the older ehci-tegra driver into the ChipIdea driver, hence
the RPM is supported by both UDC and host controllers, secondly this opens
opportunity for implementing OTG support in the future.

Patchset was tested on various Tegra20, Tegra30 and Tegra124 devices.
Thanks to Peter Geis, Matt Merhar and Nicolas Chauvet for helping with
the extensive and productive testing!
