[PATCH 3/8] video: tegra: Rework some of the driver dependencies

[Tom Rini]

Looking these drivers over, all of them cannot build without access to
some platform specific header files. Express those requirements in
Kconfig as well. Furthermore, update the logic a bit more to reflect
which parts are optional when other drivers are enabled and which parts
cannot be enabled (meaningfully) by themselves.
