Log Message:
acpi: Try PSCI before UEFI RT for shutdown/reset.
BSA says that an OS can use either UEFI RT or PSCI, and that the RT
implementation should just call PSCI.
Given the amount of implementation issues with UEFI RT, let's try PSCI
first, because it's nice to be able to reboot and poweroff even with
buggy firmware.
