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, Nicolas Chauvet and Ion Agorria for
helping with the extensive and productive testing!

Changelog:

v2: - Improved comments in the code as it was suggested by Peter Chen and
      Sergei Shtylyov for v1.

    - Replaced mdelay() with fsleep() and made ci->hdc to reset to NULL in
      a error code path, like it was suggested by Peter Chen.

    - Redirected deprecated USB_EHCI_TEGRA Kconfig entry to USB_CHIPIDEA_TEGRA
      as was suggested by Alan Stern.

    - Improved commit message and added ACK from Thierry Reding to the patch
      that removes MODULE_ALIAS.

    - Fixed UDC PHY waking up on ASUS TF201 tablet device by utilizing
      additional VBUS sensor. This was reported and tested by Ion Agorria.

    - Added t-b from Ion Agorria.
