Nicholas Piggin 04019bf8eb powerpc: Add irq accounting for watchdog interrupts
This adds an irq counter for the watchdog soft-NMI. This interrupt
only fires when interrupts are soft-disabled, so it will not
increment much even when the watchdog is running. However it's
useful for debugging and sanity checking.
