watchdog: Convert to using sbintime_t formatHEADmain

Summary:
Some watchdogs are now based on a countdown timer instead of a bit
check.  To deal with these, convert the watchdog framework to use
sbintime_t instead of power-of-2-nanoseconds.  This allows more
precision, and more variety of watchdog timeouts.  Keep the old method
as a compatibility layer, so that drivers can be migrated slowly, as
needed.
