arm: zynq: Try to enable the first watchdog via aliases
The same change as was done for zynqmp with this description:
Add support for enabling the first watchdog pointed via aliases.
DT fragment:
aliases {
...
watchdog0= &watchdog0;
watchdog1 = &watchdog_lpd;
...
};
<zynqmp example removed>
Till this patch the first watchdog found in DT was used and started
which is not enabling all possible configuration based on user request.
