[WATCHDOG] wdt_pci.c: remove #ifdef CONFIG_WDT_501_PCI

Change the wdt_pci.c watchdog driver so that the code is the same for
both the PCI-WDT500 as the PCI-WDT501 card. The selection of the card
is now being done via the module parameter: 'type' instead of the
config option CONFIG_WDT_501_PCI.

-         you a thermometer inside your computer: reading from

-         Fahrenheit. This works only if you have a PCI-WDT501 watchdog board
-         installed.
+         If you have a PCI-WDT501 watchdog board then you can enable the
+         temperature sensor by setting the type parameter to 501.
 
          If you want to enable the Fan Tachometer on the PCI-WDT501, then you
          can do this via the tachometer parameter. Only do this if you have a
          fan tachometer actually set up.
