[PATCH 1/2] x86/apic: remove declaration of unused hw_nmi_is_cpu_stuck

[Yaowei Bai]

Commit 10f9014912 ("x86: Cleanup hw_nmi.c cruft") removed unused
code in the hw_nmi.c file because of the redesign of the hardlockup
watchdog but left declaration of hw_nmi_is_cpu_stuck in linux/nmi.h,
so remvoe it.

[PATCH 2/2] x86/dma: is_device_dma_capable can be boolean

[Yaowei Bai]

This patch makes is_device_dma_capable return bool to improve
readability due to this particular function only using either
one or zero as its return value.

No functional change.
