In order to make subsystem-wide changes easier, move the Tegra DRM
driver back into the DRM tree.
Signed-off-by: Thierry Reding <treding@nvidia.com>

The Tegra DRM driver currently uses some infrastructure to defer the DRM
core initialization until all required devices have registered. The same
infrastructure can potentially be used by any other driver that requires
more than a single sub-device of the host1x module.
Make the infrastructure more generic and keep only the DRM specific code
in the DRM part of the driver. Eventually this will make it easy to move
the DRM driver part back to the DRM subsystem.

Expose the buffer objects, syncpoint and channel functionality in the
public public header so that drivers can use them.

This structure derives from host1x_client. DRM-specific fields are moved
from host1x_client to this structure, so that host1x_client can remain
agnostic of DRM.

Most of the included files are either not required or already included
by some other header file.

The host1x and Tegra DRM drivers are currently tightly coupled. Renaming
the structure marks the boundary more clearly.

drm/tegra: Changes for v3.12-rc1
Only a couple of small patches this time around. These are mostly fixes
for minor bugs that showed up, but there is also some preparatory work
that will come in handy for future patches.
* tag 'drm/for-3.12-rc1' of git://anongit.freedesktop.org/tegra/linux:
drm/tegra: Parse device tree earlier
gpu: host1x: Sort drivers by probe order
gpu: host1x: Check for valid host1x pointer
gpu: host1x: returning success instead of -ENOMEM
gpu: host1x: fix an integer overflow check
drm/tegra: hdmi: Make sure clock is enabled before dumping registers

We just got rid of the version of hdmi_vendor_infoframe that had a byte
array for anyone to poke at. It's now time to shuffle around the naming
of hdmi_hdmi_infoframe to make hdmi_vendor_infoframe become the HDMI
vendor specific structure.

I just wrote the bits to define and pack HDMI vendor specific infoframe.
Port the host1x driver to use those so I can refactor the infoframe code
a bit more.
This changes the length of the infoframe payload from 6 to 5, which is
enough for the "frame packing" stereo format.
v2: Pimp up the commit message with the note about the length

The debugfs register dumping function did not enable the HDMI clock.
This led to a possible system hang when reading the debugfs entry
while no HDMI cable was connected to the system. This patch makes
sure that the clock is enabled during the read.

Remove second host1x driver, and bind tegra-drm to the new host1x
driver. The logic to parse device tree and track clients is moved
to drm.c.

Both host1x and drm drivers have host1x structures. This patch
renames the host1x structure under drm to follow name host1x_drm.
