The generic entry code uses preempt_count() and need_resched() helpers to
check if it should do preempt_schedule_irq(). Currently, arm64 use its own
check logic, that is "READ_ONCE(current_thread_info()->preempt_count == 0",
which is equivalent to "preempt_count() == 0 && need_resched()".
In preparation for moving arm64 over to the generic entry code, use
these helpers to replace arm64's own code and move it ahead.
No functional changes.
