rtems_configuration_smp_maximum_processors is the maximum possible in this
RTEMS application.

_SMP_Processor_count is the number actually available.

So you can have an app configured for 4 CPUs and run it on a 2 core system.

rtems_configuration_smp_maximum_processors could be part of the main
Configuration table.  That is worth considering.
