The WDAT watchdog driver uses functionality provided by the watchdog timer
core but it did not select it explicitly. This results following linker
error when only WDAT_WDT is enabled in Kconfig:

drivers/built-in.o: In function `wdat_wdt_probe':
drivers/watchdog/wdat_wdt.c:444: undefined reference to `devm_watchdog_register_device'

Fix this by explicitly selecting WATCHDOG_CORE when WDAT watchdog driver is
