ppc: make PPC_BOOK3S_64 select IRQ_WORK

Browse source 
Fix breakage which will be exposed by the patch "kconfig: make allnoconfig
disable options behind EMBEDDED and EXPERT".

arch/powerpc/kernel/mce.c, compiled in for PPC_BOOK3S_64, calls
functions only built when IRQ_WORK, so select it.  Fixes the following
build error:

  arch/powerpc/kernel/built-in.o: In function `.machine_check_queue_event':
  (.text+0x11260): undefined reference to `.irq_work_queue'
