Any particular reason why PSCI v0.2 or above is not supported on this
platform. PSCI v0.1 is very old now and I assume this platform is
relatively new.

Atleast the functions ids look like v0.2 or above. So check if it's
actually v0.2 or above in which case you can drop all the function ids above

Preferably "arm,gic-400" ?
