[PATCH v3 29/30] arm: mach-bcm283x: Enable ARMV8_MULTIENTRY

[Patrick Rudolph]

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 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.
