[U-Boot] [PATCH V2 05/13] ARM: tegra: only build __pinmux_nand() when it's needed

[Stephen Warren]

From: Tom Warren <twarren.nvidia at gmail.com>

__pinmux_nand() won't compile if PERIPH_ID_NDFLASH isn't defined.
Prevent this from causing build problems on newer SoCs without NAND
support (or without SW support for NAND yet), but preventing
compilation unless the function will actually be used, i.e. when
CONFIG_TEGRA_NAND is defined.

[swarren, rewrote commit description, moved ifdef around whole function
rather than just body]

v2:
* Fixed TODO by moving the ifdef around the whole function rather than
  being inside the function body. The call to the function is under the
  same ifdef.
