sched/preempt: Decouple HAVE_PREEMPT_DYNAMIC from GENERIC_ENTRY
Now that the enabled/disabled states for the preemption functions are
declared alongside their definitions, the core PREEMPT_DYNAMIC logic is
no longer tied to GENERIC_ENTRY, and can safely be selected so long as
an architecture provides enabled/disabled states for
irqentry_exit_cond_resched().
Make it possible to select HAVE_PREEMPT_DYNAMIC without GENERIC_ENTRY.
For existing users of HAVE_PREEMPT_DYNAMIC there should be no functional
change as a result of this patch.
