[PATCH 2/5] watchdog: watchdog_core: make it explicitly non-modular

[Paul Gortmaker <paul.gortmaker@windriver.com>]

The Kconfig currently controlling compilation of this code is:

config WATCHDOG_CORE
       bool "WatchDog Timer Driver Core"

...meaning that it currently is not being built as a module by anyone.

Lets remove the modular code that is essentially orphaned, so that
when reading the driver there is no doubt it is builtin-only.

We replace module.h with export.h since the file does export some
symbols.  We don't add init.h since the file already has that.

We also delete the MODULE_LICENSE tag etc. since all that information
is already contained at the top of the file in the comments.
