[Discuss OpenCPI] Multiple ad9361_config_proxy Instances

I'm guessing this is an issue with how the framework maps the HDL
slave's memory as made available to the RCC proxy. I know there are
some differences in the C++ classes for management of simulator vs
FPGAs, and it seems I need to exercise the latter to recreate the
problem.

It may be helpful to look at your application XML.

Just to be clear, this seems to be an RCC issue and not an HDL issue.

I believe the HDL is doing exactly what it should be doing, but the
proxy worker on the RCC/ARM side seems to want to point to the last
initialized device.

If you need me to run some commands to help figure this out, please
let me know. I can provide logs.

Thanks,
Brian
