arm64: dts: Reserve the memory used for secondary CPU release address
With the spin-table SMP booting method, secondary CPUs poll a location passed in the DT. The foundation-v8.dts file doesn't have this memory reserved and there is a risk of Linux using it before secondary CPUs are started. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
