watchdog: tqmx86_wdt: Fix build error

commit 9a6c274ac1c4346f5384f2290caeb42dc674c471 upstream.

If TQMX86_WDT is y and WATCHDOG_CORE is m, building fails:

drivers/watchdog/tqmx86_wdt.o: In function `tqmx86_wdt_probe':
tqmx86_wdt.c:(.text+0x46e): undefined reference to `watchdog_init_timeout'
tqmx86_wdt.c:(.text+0x4e0): undefined reference to `devm_watchdog_register_device'

Select WATCHDOG_CORE to fix this.
