drivers: PSCI: Add driver and subsystem Firmware implementing the PSCI functions described in ARM document number ARM DEN 0022A ("Power State Coordination Interface System Software on ARM processors") can be used by Zephyr to initiate various CPU-centric power operations. It is needed for virtualization, it is used to coordinate OSes and hypervisors and it provides the functions used for SMP bring-up such as CPU_ON and CPU_OFF. A new PSCI driver is introduced to setup a proper subsystem used to communicate with the PSCI firmware, implementing the basic operations: get_version, cpu_on, cpu_off and affinity_info. The current implementation only supports PSCI 0.2 and PSCI 1.0 The PSCI conduit (SMC or HVC) is setup reading the corresponding property in the DTS node.
