Peter Maydell d6dc926e6e hw/arm/boot: Drop nb_cpus field from arm_boot_info 
We use the arm_boot_info::nb_cpus field in only one place, and that
place can easily get the number of CPUs locally rather than relying
on the board code to have set the field correctly.  (At least one
board, xlnx-versal-virt, does not set the field despite having more
than one CPU.)
