watchdog: fix several MODULE_PARM_DESC strings
Fix MODULE_PARM_DESC() strings in several watchdog drivers. Some are simple as add a parenthesis. Others are problems from __stringify() being used on a variable name instead of a macro name, so the variable name is produced in the string instead of its build-time value. In these cases, create a macro for the value so that the module param description string is useful. Only pc87413_wdt has been built (due to toolchains).
