Subject: [PATCH] ARM: tegra: Guard GP pad control code with a Kconfig symbol

The GP pad control 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.
