Douglas Anderson df8b78e163 powerpc: move arch_trigger_cpumask_backtrace from nmi.h to irq.h 
The powerpc architecture was the only one that defined
arch_trigger_cpumask_backtrace() in asm/nmi.h instead of
asm/irq.h. Move it to be consistent.

This fixes compile time errors introduced by commit 7ca8fe94aa
("watchdog/hardlockup: define HARDLOCKUP_DETECTOR_ARCH"). That commit
caused <asm/nmi.h> to stop being included if the hardlockup detector
wasn't enabled. The specific errors were:
  error: implicit declaration of function `nmi_cpu_backtrace'
  error: implicit declaration of function `nmi_trigger_cpumask_backtrace'

NOTE: when moving this into irq.h, we also change the guards from just
checking if "CONFIG_NMI_IPI" is defined to also checking if
"CONFIG_PPC_BOOK3S_64" is defined. This matches the code in
arch/powerpc/kernel/stacktrace.c. Previously this worked because
<asm.nmi.h> was included if "CONFIG_HAVE_HARDLOCKUP_DETECTOR_ARCH" was
defined. For powerpc that's only selected if "CONFIG_PPC_BOOK3S_64" is
defined.

[dianders@chromium.org: change the guards to include CONFIG_PPC_BOOK3S_64]
