[PATCH 16/17] arm: mach-bcm283x: Enable ARMV8_MULTIENTRY

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 to use the ACPI parking protocol instead.

TEST: - Aps enter U-Boot when run on qemu-system-aarch64 -machine raspi4b
      -	APs on real hardware do not enter U-Boot! To be investigated.
