Move the check of the permission to change a config object from zynqmp_pmufw_node function to zynqmp_pmufw_load_config_object function to simplify the code and check the permission only if required.

This is not right. It should be return zynqmp_pmufw_load... for error propagation.
At the moment the zynqmp_pmufw_node and zynqmp_pmufw_config_close doesn't return an error. Should the zynqmp_pmufw_load_config_object return 0 or -EACCES if it is skipped?
