ARM: tegra: Guard pin controller code with a Kconfig symbol

Browse Source 
Pin controller code is not relevant on all Tegra SoC generations, so
guard it with a Kconfig symbol that can be selected by the generations
that need it.

This is in preparation for unifying Tegra186 code with the code used on
older generations.
