arm64: dts: Reserve the memory used for secondary CPU release address
commit df503ba7f653c590b475ab80bde788edf5af70d5 upstream.
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.
