I'm not so sure that this area will remain small. I suspect we'll see
a reasonable amount of sharing for arm/arm64 where two SoCs differ sith
s/Cortex-A7/Cortex-A53/, for example.

Perhaps we could wait until the that starts to happen; we managed to
survive for a while before moving arm64's dts into subdirs.

If we think it is inevitable we may as well bite the bullet, plus I've
already done "git commit --amend" to move it to include/dt-dtsi/arm ;-)
