[PATCH 11/21] powerpc: Add missing prototype for hdec_interrupt

[Mathieu Malaterre]

In commit dabe859ec636 ("powerpc: Give hypervisor decrementer interrupts
their own handler") an empty body function was added, but no prototype was
declared. Fix warning (treated as error in W=1):

  CC      arch/powerpc/kernel/time.o
arch/powerpc/kernel/time.c:629:6: error: no previous prototype for ‘hdec_interrupt’ [-Werror=missing-prototypes]
 void hdec_interrupt(struct pt_regs *regs)
      ^~~~~~~~~~~~~~
cc1: all warnings being treated as errors
