watchdog: da9055_wdt needs to select WATCHDOG_CORE

DA9055_WATCHDOG (introduced in v3.8) needs to select WATCHDOG_CORE so that it will
build cleanly.  Fixes these build errors:

da9055_wdt.c:(.text+0xe9bc7): undefined reference to `watchdog_unregister_device'
da9055_wdt.c:(.text+0xe9f4b): undefined reference to `watchdog_register_device'
