dt-bindings: watchdog: qcom-wdt: allow interrupts

Both of type of watchdogs described in the binding (the KPSS watchdog
and APSS WDT timer) have interrupts.  Allow interrupts and describe them
for KPSS watchdog to fix warnings like:

  watchdog@17c10000: Unevaluated properties are not allowed ('interrupts' was unexpected)
