watchdog: Prefix WDT with ICS for clarity

`wdt.rst` is only about the Watchdog from "Industrial Computer Source"
(ICS). Change the title and rename the file to better express this.

Add missing SPDX license identifier `GPL-2.0-or-later` same as code to
silence `checkpatch`.

Fix wrong link to sample driver in drivers/watchdog/smsc37b787_wdt.c.
