A previous change of the sama5d4_wdt driver broke the device probing with the device tree configuration described in existing DTS files, when no value is set for the "timeout-sec" property. Moreover, specifying any other value than 16 seconds for "timeout-sec" leads to a watchdog reset immediately when opening the watchdog device. Fix this by respecting hardware constraints added in recent versions of the SAMA5D2 and SAMA5D4 datasheet.
