powerpc: Add missing prototype for hdec_interrupt

Browse Source 
In commit dabe859ec6 ("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):

  arch/powerpc/kernel/time.c:629:6: error: no previous prototype for ‘hdec_interrupt’
