Add the DT entry for a watchdog based on RTI1.

On SR1.0 silicon, it requires additional firmware on the MCU R5F cores
to handle the expiry, e.g. https://github.com/siemens/k3-rti-wdt. As
this firmware will also lock the power domain to protect it against
premature shutdown, mark it shared.

Jan, I was about to pick up the patches and was running through
my sanity checks and the following caught my eye with dtbs_check
(dtschema is at 2021.2.1) test against next-20210311

/workdir/arch/arm64/boot/dts/ti/k3-am654-base-board.dt.yaml: rti@40610000: $nodename:0: 'rti@40610000' does not match '^watchdog(@.*|-[0-9a-f])?$'

Please use watchdog@40610000 instead of rti@40610000

Since this is a minor change, I have done this change locally. let me
know if you have an issue and I can drop it off my branch for a new
version.
