powerpc: Respect nr_cpu_ids when calling set_cpu_possible and set_cpu_present
We should not set cpus above nr_cpu_ids to possible. While we
will trigger a warning with CONFIG_CPUMASK_DEBUG, even then the mask
initializers will set the bits beyond what the iterators check and cause
nr_cpu_ids to increase.
Respecting nr_cpu_ids during setup will allow us to use it in our initial
paca allocation. It can be reduced from NR_CPUS by the existing early param
nr_cpus=, which was added in 2b633e3fac5efada088b57d31e65401f22bcc18f (smp:
Use nr_cpus= to set nr_cpu_ids early). We already call parse_early_parms
between finding the command line and allocating the pacas.
