Mask the expected and show the unexpected warning "No permission to
change config object" for PMUFW_CFG_OBJ_SUPPORT_NODE because this node
is used to detect if further zynqmp_pmufw_node function calls should be
skipped.

When only this patch is applied you return -EACCES but for setting up
skip_config=true you need to return XST_PM_NO_ACCESS.
It means you are changing system behavior not just message that's why I still
think it should be together with 3/3.
Anyway take a look at my snipset how I think it could be done in cleaner way.
Thanks,
