For implementations complying to PSCI 0.2.
Function IDs are not required and should be ignored by an OS with
PSCI 0.2 support, but are permitted to be present for compatibility
with existing software when "arm,psci" is later in the compatible
list.

For implementations complying to PSCI 1.0.
PSCI 1.0 is backward compatible with PSCI 0.2 with minor

description: The method of calling the PSCI firmware.
Even PSCI v1.0 compliant implementations may support v0.1 clients (i.e. "arm,psci"). Relax the compatible schema such that an implementation can claim 1.0, 0.2, and 0.1 compatibility. In the process, the schema can be simplified a bit by using 'minItems' instead of separate 'oneOf' entries.
