watchdog: imgpdc: Fix default heartbeat
The IMG PDC watchdog driver heartbeat module parameter has no default so it is initialised to zero. This results in the following warning during probe: imgpdc-wdt 2006000.wdt: Initial timeout out of range! setting max timeout The module parameter description implies that the default value should be PDC_WDT_DEF_TIMEOUT, which isn't yet used, so initialise it to that. Also tweak the heartbeat module parameter description for consistency.
