Subject: [PATCH] arm: Add missing method to asm/irq_work.h

Add missing method arch_irq_work_raise() to irq_work.h, so as to remove
missing-prototypes warning in kernel/smp.c.

../arch/arm/kernel/smp.c:572:6: warning: no previous prototype for ‘arch_irq_work_raise’ [-Wmissing-prototypes]
 void arch_irq_work_raise(void)
      ^~~~~~~~~~~~~~~~~~~
