fix(fvp): allow PSCI 0.2 in the device tree

Although the platform assumes it will use the device tree hosted with
it, there are device trees out there (eg in Linux) that will also work
just fine. Some of them, unfortunately, specify PSCI 0.2, but FCONF
performs a fatal check for 1.0. Add a fallback to 0.2 so that those
device trees can work.
