I don't particularly object to the patch but this occurred to me too. I
suppose the rule is "first sunxi to look this way".

How about we call groups of similar SoCs a "generation", i.e.
ARCH_SUNXI_GEN2 is what is called ARCH_SUN6I here, meaning GEN1 would be
SUN4/5/7I.

I've deliberately not considered SUN1/2/3I since I don't know much about
them, and we don't support them AFAIK, but perhaps the generation
numbers I've picked should be larger to accommodate them.

Ian.
