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. Signed-off-by: Girisha Dengi <girisha.dengi@intel.com> Signed-off-by: Navinkumar Balabakthan <navinkumar.balabakthan@intel.com>
