My primary motivation was to bring Tegra into line with what appears to
be common practice amongst other ARM sub-architectures; many of
mach-$x/include/mach/gpio-$x.h define the GPIO names there.

Still, your argument is valid; I don't foresee a need to anything other
than mach-tegra/*.c to need the GPIO names file.

So, feel free to take/drop this patch as you desire.
