drivers: pm_cpu_ops: Add support for multiple PSCI versions

Each PSCI interface versions have different DT compatible strings
like arm,psci-0.2, arm,psci-1.1 and so on. However, the same driver
can be used for all the versions by adding #define DT_COMPAT for
required version and #undef DT_COMPAT for default version.

Add support for PSCI cold reset, warm reset and cpu-on function IDs.
