Upstream has already moved everything to the new location; a vanilla
kernel does not have the include/asm-arm/arch-s3c2410 directory
anymore.  Everything that's lagging is Moko stuff.  Anyway, git is
pretty smart about these things.  Even if somebody else were to do the
same move, the changes would match and git-rebase would just discard
the patch.  What we get from this is a chance to see when changes that
clash with Moko work are landing upstream... with the two separate
directories we were missing this.
