Christophe Leroy (CS GROUP) a2c02aa0c6 powerpc: Remove dead non-preemption code 
Since commit 7dadeaa6e8 ("sched: Further restrict the preemption
modes"), powerpc always has CONFIG_PREEMPTION because only
CONFIG_PREEMPT and CONFIG_PREEMPT_LAZY are possible, even in
dynamic preemption mode (see sched_dynamic_mode).

As a consequence, need_irq_preemption() is always true and can be
removed.

And because commit bee25f97ad ("powerpc: Enable GENERIC_ENTRY
feature") includes linux/irq-entry-common.h which already declares
sk_dynamic_irqentry_exit_cond_resched static key, asm/preempt.h
becauses useless and can be removed.
