Enable the hardclock-based watchdog previously conditional on the SW_WATCHDOG option whenever hardware watchdogs are not found, and watchdogd attempts to enable the watchdog. The SW_WATCHDOG option still causes the sofware watchdog to be enabled even if there is a hardware watchdog. This does not change the other software-based watchdog enabled by the --softtimeout option to watchdogd. Note that the code to reprime the watchdog during kernel core dumps is no longer conditional on SW_WATCHDOG. I think this was previously a bug.
