drm/tegra: Changes for v3.19-rc1

Browse source 
The highlights in this pull request are:
 
   * IOMMU support: The Tegra DRM driver can now deal with discontiguous
     buffers if an IOMMU exists in the system. That means it can allocate
     using drm_gem_get_pages() and will map them into IOVA space via the
     IOMMU API. Similarly, non-contiguous PRIME buffers can be imported
     from a different driver, which allows better integration with gk20a
     (nouveau) and less hacks.
 
   * Universal planes: This is precursory work for atomic modesetting and
     will allow hardware cursor support to be implemented on pre-Tegra114
     where RGB cursors were not supported.
 
   * DSI ganged-mode support: The DSI controller can now gang up with a
     second DSI controller to drive high resolution DSI panels.
 
 Besides those bigger changes there is a slew of fixes, cleanups, plugged
 memory leaks and so on.
