watchdog: remove Kconfig.defconfig setting of watchdog drivers

Now that watchdog drivers are enabled based on devicetree
we need to remove any cases of them getting enabled by
Kconfig.defconfig* files as this can lead to errors.

Typically the Kconfig.defconfig* will blindly enable a
watchdog and not respect the devicetree state of the watchdog.
Additionally we can get problems with prj.conf/defconfig
getting incorrectly overridden.
