arm: dts: k3: Add RTI watchdogs

Add DT entries for main domain watchdog0 and 1 instances on the J721e
well as RTI1-based watchdog on the AM65x. RTI0 does not work for this
purpose on the AM65x, so leave it out.

On AM65x, we mark the power-domain as shared because RTI firmware such
as https://github.com/siemens/k3-rti-wdt may request it as well in order
to prevent accidental shutdown of the watchdog.
