[U-Boot] [PATCH v2 03/15] ARM: tegra: Guard GP pad control code with a Kconfig symbol

From: Thierry Reding <treding at nvidia.com>
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.
