So, in applying
https://patchwork.ozlabs.org/project/uboot/patch/20210910213743.30793-1-trini@konsulko.com/
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.
