ARM: tegra: move ft_system_setup()
Currently, ft_system_setup() is implemented by board*.c, which are a bit
of a dumping ground for a bunch of unrelated functionality, and separate
versions exist for pre-Tegra186 and Tegra186. Move the implementation into
a separate file to separate functionality, and allow sharing.
