1. Because size-cells is no need to use 2, modify to 1 for use.
2. Add minItems to 1 for interrupts for intc1.
3. Add 1 interrupt of intc1 example into yaml file.
4. Add intc1 sub-module of uart12 as example using the intc0 and intc1.

As with all your patches, repeating since v1 the same comment, so one
more last time:

Please run scripts/checkpatch.pl and fix reported warnings. Then please
run 'scripts/checkpatch.pl --strict' and (probably) fix more warnings.
Some warnings can be ignored, especially from --strict run, but the code
here looks like it needs a fix. Feel free to get in touch if the warning
is not clear.

Best regards,
Krzysztof
