Whack-a-mole some more occurrences of status in examples.

* AppliedMicro X-Gene PCIe interface
Required properties:
- device_type: set to "pci"
- compatible: should contain "apm,xgene-pcie" to identify the core.
- reg: A list of physical base address and length for each set of controller
registers. Must contain an entry for each entry in the reg-names
property.
- reg-names: Must include the following entries:
"csr": controller configuration registers.
"cfg": PCIe configuration space registers.
- #address-cells: set to <3>
- #size-cells: set to <2>
- ranges: ranges for the outbound memory, I/O regions.
- dma-ranges: ranges for the inbound memory regions.
- #interrupt-cells: set to <1>
- interrupt-map-mask and interrupt-map: standard PCI properties
to define the mapping of the PCIe interface to interrupt
numbers.
- clocks: from common clock binding: handle to pci clock.
Optional properties:
- status: Either "ok" or "disabled".
- dma-coherent: Present if DMA operations are coherent
Example:
pcie0: pcie@1f2b0000 {
status = "disabled";
device_type = "pci";
compatible = "apm,xgene-storm-pcie", "apm,xgene-pcie";
#interrupt-cells = <1>;
#size-cells = <2>;
#address-cells = <3>;
