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.
