[PATCH 3/3] misc: ppc/spapr: replace qemu_system_reset_request() calls with watchdog_perform_action()

[Abhiram Tilak]

A few watchdog devices use qemu_system_reset_request(). This is not ideal since
behaviour of watchdog-expiry can't be changed by QMP using `watchdog_action`.
As stated in BiteSizedTasks wiki page, instead of using 
qemu_system_reset_request()
to reset when a watchdog timer expires, let watchdog_perform_action() decide
what to do.

I am unsure about the changes in `spapr_watchdog.c` in patch 3, it would be 
great
if any of the maintainers review it.
