[U-Boot] [PATCH 35/60] nyan-big: remove direct MC register access

[Stephen Warren]

From: Stephen Warren <swarren at nvidia.com>

Equivalent code is already present in the core Tegra board file, so
there's no point repeating it here. This removes the only use of
<asm/arch/mc.h> from outside arch/arm/mach-tegra/.
