OK sounds like we need to use some different SoC specific .dtsi file,
is this maybe x15 rev c?

You can detect which modules fail based on the module base address
for revision register seen with the following debug patch. Then
those need to be tagged with status = "disabled" at the module
level in the SoC specific dtsi file.
