Add the DT entry for a watchdog based on RTI1. 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.
Aligns us to the kernel's DT in this regard.

So, in applying https://patchwork.ozlabs.org/project/uboot/patch/20210910213743.30793-1-trin... to bring us fully to v5.14 for K3 platforms, this patch is no longer needed, and I'm deferring it. The only difference is the node name is "watchdog@40610000" not "rti@40610000" but should not matter (and doesn't look to from a quick read of the rest of the series.
Ack, this is now obsolete.
