video: tegra: Rework some of the driver dependencies

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.
