Can we configure/change this field in platform specific .dts file?
OR
Is there condition based configuration possible in DT?

To be specific,

I am adding support for AM335x EVM (using all your DT support patches),
The device is considered as OMAP3 variant and when it comes to INTC support,
I need to configure it to value "128", rest everything is same 
(including base add).

Can I do something like

File - am335x-evm.dts

/include/ "omap3.dtsi"

....
Again change the specific fields of " intc: interrupt-controller"?
....

How can this be handled?

Thanks,
Vaibhav
