powerpc/64e/interrupt: NMI save irq soft-mask state in C
64e non-maskable interrupts save the state of the irq soft-mask in
asm. This can be done in C in interrupt wrappers as 64s does.
I haven't been able to test this with qemu because it doesn't seem
to cause FSL bookE WDT interrupts.
This makes WatchdogException an NMI interrupt, which affects 32-bit
as well (okay, or create a new handler?)
