nyan: Add a kconfig for building for the original nyans in pixel cases.

The variable defaults to off because this will very much be the common case.
It's set to y in the nyan config at the moment, though, since the pixel
versions are the most common for now.

BUG=None
TEST=With this and other changes built and booted on old and new nyan boards.
BRANCH=None
