watchdog: sunxi: fix activation of system reset
Commit f2147de33470 ("watchdog: sunxi: support parameterized compatible strings") introduced a regression in sunxi_wdt_start(), by which the system reset function of the watchdog is not enabled upon starting the watchdog. As a result, the system is not reset when the watchdog expires. Fix it.
