[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.

Saying Y here and creating a character special file /dev/temperature

you a thermometer inside your computer: reading from
/dev/temperature yields one byte, the temperature in degrees
Fahrenheit. This works only if you have a PCI-WDT501 watchdog board
installed.
