powerpc/watchdog: Declare soft_nmi_interrupt() prototype



soft_nmi_interrupt() usage requires PPC_WATCHDOG to be configured.
Check the CONFIG definition to declare the prototype.

It fixes this W=1 compile error :

../arch/powerpc/kernel/watchdog.c:250:6: error: no previous prototype for ‘soft_nmi_interrupt’ [-Werror=missing-prototypes]
  250 | void soft_nmi_interrupt(struct pt_regs *regs)
      |      ^~~~~~~~~~~~~~~~~~
