On FDT platforms the APs are brought out of reset using the spin-table as defined in the DT. On ACPI enabled platforms there's no FDT, thus enable the ARMV8_MULTIENTRY and BLOBLIST to use the ACPI parking protocol instead.
TEST: - APs enter Linux when run on qemu-system-aarch64 -machine raspi4b - APs on real hardware do not enter Linux, but continue spinning in their ACPI parking protocol spinloop. To be investigated.
