Not being aligned to 4k or 1k raises red flags.

The watchdog is part of the timer block (on this chip it's
"qcom,kpss-timer"). We should add qcom,kpss-wdt to the compatible
list in the timer binding and extend that binding to have clocks
and timeout-sec (watchdog-timeout-sec?). This would follow DT
best practices of having one node per device. We could also add
the interrupts too, even if they're not used by the driver right
now.
