This is a long overdue driver model conversion for the shwdt watchdog
driver. This is the initial conversion, more incremental changes to
follow.

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).

The wdt mmaping thing was a special-cased hack that nothing in the wild
depends on, so just kill it off. While at it, sanitize the superfluous
comments in preparation for a driver rewrite and overhauled interface.

This brings the watchdog drivers into line with coding style.
This patch takes cares of the indentation as described in chapter 1.
Main changes:
* Re-structure the ioctl switch call for all drivers as follows:
switch (cmd) {
case WDIOC_GETSUPPORT:
case WDIOC_GETSTATUS:
case WDIOC_GETBOOTSTATUS:
case WDIOC_GETTEMP:
case WDIOC_SETOPTIONS:
case WDIOC_KEEPALIVE:
case WDIOC_SETTIMEOUT:
case WDIOC_GETTIMEOUT:
case WDIOC_GETTIMELEFT:
default:
}
This to make the migration from the drivers to the uniform watchdog
device driver easier in the future.
