the trouble is that watchdog.h doesnt seem to match, nor does the
name.  "hardware" means to me "hardware" as in "the cpu hardware".

#ifdef CONFIG_HW_WATCHDOG
...
#else
    /*
     * Maybe a software watchdog?
     */
...
#endif

i dont see how a watchdog in the SoC could be a "software" watchdog or
a "non-hardware" watchdog.

the watchdog system is a legacy mess, so probably be easier to just
gut the whole thing.
