I suspect that you have not added the new file to git repository - since
you only removed lines from board/samsung/odroid/setup.h
I also guess that odroid U3 will not build anymore. That is a very good
use case for buildman script.

Relative path is not a good idea IMHO.
It would be better to place it at ./include/samsung/ with a self
explanatory name (like exynos4-pll.h or/and exynos4-{other excluded
defines for an IP blocks}).
In this way other boards could use those defines too.

The above data is common for Exynos U3 and XU3, but is it the only one?
Aren't there any more defines to be extracted?
