This looks good, but has the unfortunate effect of leaving the
(irrelevant) cpu-release-addr property in the PSCI dts files, as that's
in the underlying dtsi file.

Could we split spin-table / PSCI parts into separate dtsi files?

e.g. have:

* foundation-v8.dtsi
* foundation-v8-gicv{2,3}.dtsi
* foundation-v8-{psci,spin-table}.dtsi

... and then combine those to build the dts files we want.

FWIW, with that:
