So far we have hard coded the DT platform parsing code in

I'm pretty sure you're doing this because you want to use
coresight_alloc_conns() for ACPI as well, and I'm fine with that. But it is
quite orthogonal to the rest of the work done in this patch and as such I think
it needs a patch of its own.
Sure, will split this into a separate patch.
