[PATCH 4.4 v1 09/17] cpufreq/pasemi: Adjust system_state check

[Kazuhiro Hayashi]

From: Thomas Gleixner <tglx@xxxxxxxxxxxxx>

commit d04e31a23c3c828456cb5613f391ce4ac4e5765f upstream.

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 pas_cpufreq_cpu_exit() to handle the extra
states.
