drivers: media: tegra: Tegra Camera framework

Tegra camera device register - Takes care of
necessary initialization to work with common
framework for tegra

Tegra camera v4l2device register - Takes care of
v4l2 subdevice initialization and Async framework
initialization to bind with v4l2device.
In addition, tegra camera control layer is setup
for the sensor drivers to add controls selectively.
As next step all the v4l2 controls in tegra camera
drivers will be added here.

The common framework initializes the drivers based
on the device tree properties to setup for each
sensor mode.
