firmware: zynqmp: Do not report error if node is already configured
Power domain driver sends PM fragment to PMUFW. It is sent for every node which is listed in DT. But some nodes could be already enabled but driver is not capable to find it out. That's why it blinly sents request for every listed IP. When PMUFW response by XST_PM_ALREADY_CONFIGURED error code there is no need to show any error message because node is already enabled. That's why cover this case with message when DEBUG is enabled.
