[PATCH] watchdog: aspeed_wdt: Reorder output signal register configuration

[Chin-Ting Kuo]

If the output driving type is push-pull mode, the output
polarity should be selected in advance. Otherwise, an unexpected
value will be output at the moment of changing to push-pull mode.
Thus, output polarity, WDT18[31], must be configured before
changing driving type, WDT18[30].
