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.
