The reworked RB3 Gen 2 Industrial BT UART overlay needs to disable the on-board WCN6750 PMU and add a graph endpoint to the M.2 PCI node. Label the exact WCN6750 PMU node and PCI child node connected to the M.2 E-key slot so the overlay can patch them directly instead of using a full path or reconstructing the nested PCI hierarchy.
