dt-bindings: misc: pci1de4,1: add required reg property for endpoint
The PCI subsystem links an endpoint Device Tree node to its corresponding pci_dev structure only if the Bus/Device/Function (BDF) encoded in the 'reg' property matches the actual hardware topology. Add the 'reg' property and mark it as required to ensure proper binding between the device_node and the pci_dev. Update the example to reflect this requirement.
