misc: pxa2xx_timer: replace qemu_system_reset_request() call with watchdog_perform_ac...

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.
