Hello,

This is v2 of the series to add interfaces that can be used by other drivers
to the xlnx_vcu driver. See [0] for the full motivation for this patch series.

In v2, the driver now also unregisters the registered clocks. I also dropped
the workaround for the syscon compatible in the dt bindings.

I would actually really appreciate feedback by Xilinx, because there are some
patches in the Xilinx downstream kernel that also try to expose the VCU
System-Level Control in an (IMHO) non-upstream-compatible way.

Michael
