Copy-paste, I'll fix it.

I did not add it to the few SoCs which have upstream DTS in ARM and
ARM64. I added only to the ones which are in one specific folder. Also
my patch does not affect defconfigs (qcom_defconfig and arm64/defconfig).

Whether downstream could be affected, I do not know. Anyway, what's
downstream it's the downstream's problem...
