video: tegra: config: Add Vi one device

Currently, VI registers for different two devices
called master and slave. These two devices used
independently for front and rare camera's. But hardware
has only one VI module and controls different sensors.

This has created mess in managing sensors, clks, channels,
bandwidth. Also from T21x onwards more than 2 camera
sensors controlled via single VI module. To avoid creation
those many device nodes code has been modified and protected
with CONFIG_VI_ONE_DEVICE.

This patch adds config entry into Kconfig.
