We'll drop this dt-binding header, ad move it to the dts folder.

But actually, even if we describe this in the YAML, most of the GCE
users still won't know what is the meaning of each mbox-cells.

So I think if we can keep these define to make dts more readable.
What do you think?

I think we can drop this in MT8196 because GCE hardware designer didn't
change these subsys id from the previous SoCs.

Almost all of the device register are over 0x3000_0000, so it's no
longer to use in MT8196.

Yes, it's the same meaning.

I agree with you, I'll simplify the define with post-fixed numbers, and
move it to dts folder once the mt8196.dtsi with gce node is submitted.

Thanks for your suggestion.
