Set this number to the maximum number of possible CPUs in the SoC.
SoCs may have multiple clusters with each cluster may have multiple
ports. If some ports are reserved but higher ports are used for
cores, count the reserved ports. This will allocate enough memory
in spin table to properly handle all cores.
