Well, I also thought about such approach, but there are some fundamental 
differences:
interrupt and clock controllers are completely different. Using a common 
exynos4.dtsi
and overriding them in every node will result in a code, which is a bit 
hard to follow.
IMHO with such differences justifies using separate base dtsi file.
