ppc/spapr: Implement H_WATCHDOG
The new PAPR 2.12 defines a watchdog facility managed via the new
H_WATCHDOG hypercall.
This adds H_WATCHDOG support which a proposed driver for pseries uses:
https://patchwork.ozlabs.org/project/linuxppc-dev/list/?series=303120
This was tested by running QEMU with a debug kernel and command line:
-append \
"pseries-wdt.timeout=60 pseries-wdt.nowayout=1 pseries-wdt.action=2"
and running "echo V > /dev/watchdog0" inside the VM.
