soc: defconfig: Enable WDT for ATMEL SAM MCUs

Browse source 
In Atmel SAM Family of MCUs, the watchdog is enabled by default at boot.
The watchdog once disabled, cannot be re-enabled back without a reset.
Hence disabling the Watchdog needs to be handled via the Watchdog driver.

Tested on Atmel SAMV71 Xplained Ultra Evaluation Kit.
