Bug 855811
For smoothness and rate-limiting, it is useful to synchronize input
events to flip. This patch adds a fake input device that emits an event
on each vsync. This allows the Android input framework, which has
significant infrastructure to monitor input devices in particular, to be
notified of vsync events.
Because there is no input event type/code for this behavior, we use an
undocumented protocol of emitting a single MSC_RAW type event with
scan-code 1. We also do not register ourselves for any other
buttons/keys, which should prevent our device node from being confused
with other input types.

This adds the infrasturcture for an enhanced driver interface to program
extended capabilities of the Tegra display controller.
It exposes a new set of device nodes for userspace clients distinct from
the traditional fbdev device nodes. This is necessary due to
limitations in the fbdev infrastructure that don't allow drivers to
store file-private data.

Includes:
1.) Added basic DC sysfs objects.
2.) Sysfs objects and functions for smartdimmer settings.
3.) Register dump access for smartdimmer.
4.) Improvements to the behavior of smartdimmer (now updates
at the end of vblank instead of the beginning).
5.) Rename v_blank_complete to vblank_complete to keep in
same effective style as the rest of the code.

This creates a new device node per head - /dev/tegra_dc%u. There are a
number of ioctls in linux/tegra_overlay.h to open, close, and flip
overlays.
This is a replacement for the extensions in the tegra fb interface, but
does not remove that functionality for compatibility reasons. Once
everyone has moved, we can remove the tegra fb extensions.

Device /dev/nvhdcpX is used to manage NVHDCP on framebuffer /dev/fbX.
These devices are created on hdmi driver initialition when it is
attached to dc. An ioctl interface is in video/nvhdcp.h
Hooks into edid.c and hdmi.c were added to take control of I2C bus.
use TEGRA_DC_OUT_NVHDCP_POLICY_ON_DEMAND in tegra_dc_out.flags in board
panel configuration to select a different default policy at probe.

Notable ommisions:
* support for anything but lvds panels
* inegration with nvhost driver to sync updates with 3D
* FB physical geometry is not set
* lacks interface to set overlay/window x,y offset
v2 changes:
* suspend/resume support
* move code into drivers/video/tegra/dc
* modularize output support
* clean register dumping, add debugfs register file
* code review feedback
* make the display controller register the framebuffer devices
