Subject: [PATCH V2 2/6] cpuidle/pseries: Remove dependency of pseries.h file

As a part of pseries_idle cleanup to make the backend driver
code common to both pseries and powernv, this patch
is essential to remove the dependency of pseries.h
header file.

Move the declaration of smt_snooze_delay from pseries.h
to processor_idle.c. smt_snooze_delay variable is
needed for both pseries and powernv.

/* Snooze Delay, pseries_idle */
DECLARE_PER_CPU(long, smt_snooze_delay);
