[PATCH v1] arm: dts: fsl-lx2160a: wdt0 for watchdog node

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 at 23a0000}.

It fails with
  Label or path /soc/watchdog at 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.
