Currently if the Foundation model is running ARM Trusted Firmware then
the kernel, which is configured to use spin tables, cannot start secondary
processors or "power off" the simulation.

Add a couple of labels to the include file, and introduce a new .dts
file that uses these to override the enable-method.

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.

Will do.

FWIW, with that:

Talking about what we want... if it's all split out I might as well add 
a gicv2+psci DT as well. Will that still retain your Acked-by or do you 
want to see it first ;-) ?
