When set, the former signals to the OS that the hardware is PSCI compliant. The latter selects the appropriate conduit for PSCI calls by toggling between Hypervisor Calls (HVC) and Secure Monitor Calls (SMC). FADT table contains such information, parse FADT to get the flags for PSCI init. Since ACPI 5.1 doesn't support self defined PSCI function IDs, which means that only PSCI 0.2+ is supported in ACPI. At the same time, only ACPI 5.1 or higher verison supports PSCI, and FADT Major.Minor version was introduced in ACPI 5.1, so we will check the version and only parse FADT table with version >= 5.1. If firmware provides ACPI tables with ACPI version less than 5.1, OS will be messed up with those information and have no way to bring up secondery CPUs, so disable ACPI if we get an FADT table with version less that 5.1.
