[PATCH 2/3] genirq: Export NMI APIs

From: Mayank Rungta <[email protected]>

Currently, request_nmi(), free_nmi(), enable_nmi() and disable_nmi_nosync()
are restricted to built-in kernel code because they are not exported to
loadable modules.

Export these APIs to allow loadable modules to register and manage NMIs.
This allows watchdog drivers configured as loadable modules to register
their bark interrupt as an NMI.
