Add `cpu1`, `cpu2` and `cpu3` nodes to the Corstone1000 device tree to enable support for secondary CPU cores. This update facilitates symmetric multiprocessing (SMP) support on the Corstone1000 Fixed Virtual Platform (FVP), allowing the secondary cores to be properly initialised and utilised. Only FVP platform will have SMP support and hence the secondary cpu definitions are not added to corstone1000.dtsi.
