Side note: only one compatible string for the real CPU please, running a
DT bindings check should complain about that.

AIUI, part of the purpose of ATF is to provide a nice standardised
platform interface regardless of whether you care about Secure software

uses an internal spin-table for its PSCI backend - in fact I suspect
that's probably just a copy-paste from the RPi3 port ;)
