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:

Thanks,
Mark.
