But these are not separate devices. Look:
1. parent DC:
reg = <0x56180000 0x40000>;

2. child interrupt controller:
reg = <0x56180040 0x60>;

That address is within parent.

3. Then we go to things like:
reg = <0x5618b400 0x14>, <0x5618b800 0x1c00>;

Still within parent's range and just few words in address range. That's
a clear indication that you choose few registers and call it a "device".

Best regards,
Krzysztof
