Mask the expected and show the unexpected warning "No permission to
change config object" for NODE_OCM_BANK_0 because this node is used to
detect if further zynqmp_pmufw_node function calls should be skipped.

First of all we should very likely create a macro for NODE_OCM_BANK_0 to cover
that dependency that it is used in 3 different locations which have to match.
The second is the change you have in 2/2 should be the part of this patch
because when only 1/2 is applied you change behavior.
And changes in 2/2 makes sense.
I would be even fine to move skip_config out of zynqmp_pmufw_node()
and setting up skip_config value directly in zynqmp_power_probe() not to check
in every call.
85 if (ret == XST_PM_NO_ACCESS && id == NODE_OCM_BANK_0)
86 skip_config = true;
Thanks,
