drivers/wifi/generic: Add support for CNVi dummy device ops

This change reorganizes drivers/wifi/generic to add a new
device_operations structure for dummy CNVi device. This is done to
make the organization of CNVi PCI device in devicetree consistent
with all the other internal PCI devices of the SoC i.e. without a chip
around the PCI device.

Thus, with this change, CNVi entry in devicetree can be changed from:
```
chip drivers/wifi/generic
	register "wake" = "xxyyzz"
	device pci xx.y on end # CNVi PCI device
end
```

to:

```
device pci xx.y on
	chip drivers/wifi/generic
		register "wake" = "xxyyzz"
		device generic 0 on end # Dummy CNVi device
	end
end # CNVi PCI device
```

The helper functions for ACPI/SMBIOS generation are also accordingly
updated to include _pcie_ and _cnvi_ in the function name.
