To enable smp_processor_id() and might_sleep() debug checks earlier, it's
required to add system states between SYSTEM_BOOTING and SYSTEM_RUNNING.
Adjust the system_state check in smp_generic_cpu_bootable() to handle the
extra states.

Adjust the system_state check in pas_cpufreq_cpu_exit() to handle the extra
states.
