The powerpc/platforms/pseries/mobility.c calls
watchdog_hardlockup_set_timeout_pct(), which is declared in
<asm/nmi.h>. We used to automatically get <asm/nmi.h> included, but
that changed as of commit 7ca8fe94aa92 ("watchdog/hardlockup: define
HARDLOCKUP_DETECTOR_ARCH"). Let's add the explicit include.
