[SL] I don't have much idea about dcsr nodes structure and their respective testing, also couldn't find then in T4 device tree files. I have added initial device trees. Dcsr may be added later as updation. What do you say?

I'll add them to T4, but if you look at the internal FSL SDK tree you will see they've been added for T4 & B4.
[SL] Ok, will add them.

Can you please point me to the patch or codebase where dcsr nodes are added in B4?
