The SBSA generic watchdog node is currently declared without a
label, so any per-board DTS that wants to override one of its
properties has to use path syntax &{/soc/watchdog@23a0000}.
It fails with
Label or path /soc/watchdog@23a0000 not found
when the path contains an `@`, forcing to duplicate the node.
Adding a one-line
wdt0:
label allows to override the node with
&wdt0 { ... };
(for example to change timeout-sec).
Zero impact on existing boards.
