watchdog: update/improve/consolidate watchdog driver

Move the limited watchdog driver help from kernel-parameters.txt
to Documentation/watchdog/watchdog-parameters.txt and add info to it
for all watchdog drivers except the ones that have driver-specific
files already.

Correct minor comments and MODULE_PARM_DESC() text in 2 places.

-A second temperature monitoring interface is available on the WDT501P cards
+A second temperature monitoring interface is available on the WDT501P cards.

 This provides /dev/temperature. This is the machine internal temperature in
 degrees Fahrenheit. Each read returns a single byte giving the temperature.
 
 The third interface logs kernel messages on additional alert events.

-The wdt card cannot be safely probed for. Instead you need to pass
-wdt=ioaddr,irq as a boot parameter - eg "wdt=0x240,11".
