drm/tegra: Changes for v3.13-rc1

Browse Source 
The biggest part of the changes is the decoupling of the host1x and DRM
 drivers followed by the move of Tegra DRM back to drivers/gpu/drm/tegra
 from whence it came. There is a lot of cleanup as well, and the drivers
 can now be properly unloaded and reloaded.
 
 HDMI support for the Tegra114 SoC was contributed by Mikko Perttunen.
 
 gr2d support was extended to Tegra114 and the gr3d driver that has been
 in the works for quite some time finally made it in. All pieces to run
 an OpenGL driver on top of an upstream kernel are now available.
 
 Support for syncpoint bases was added by Arto Merilainen. This is useful
 for synchronizing between command streams from different engines such as
 gr2d and gr3d.
 
 Erik Faye-Lund and Wei Yongjun contributed various small fixes. Thanks!
