[PATCH 1/2] ARM: tegra: remove Whistler support

[Stephen Warren <swarren-3lzwWm7+Weoh9ZMKESR00Q@public.gmane.org>]

From: Stephen Warren <swarren-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org>

Whistler is an ancient Tegra 2 reference board. I may have been the only
person who ever used it with upstream software, and I've just recycled
the board hardware. Hence, it makes sense to remove support from software.
