Can't generate DeviceResources file for Versal

[Quadrollopo]

I tried to generate the DeviceResources file for Versal with rapidwright DeviceResourcesExample xcvc1902
but the output will always end with a NullPointerException:

==                     Device Resources Dump: xcvc1902                      ==

I also tried different Versal devices but it will always end up like the previous output.
For other non-Versal devices the command would work fine.

Thank you for reporting this issue. I have created a workaround so that a Device Resources file can successfully be generated, you'll need this PR: #969.

A larger, more permanent fix will come a bit later.
