arm64: dts: Reserve the memory used for secondary CPU release address

Browse Source 
commit df503ba7f6 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.
