drivers/net/r8168: add ACPI _STA field entry
Add _STA field entry for r8168 ACPI device and set to
ACPI_STATUS_DEVICE_HIDDEN_ON in order to hide device from
OS (Windows) as there is no driver needed (or available).
Windows correctly attaches drivers to the PCIe device, the
separate ACPI device is unused and unneeded.
Linux is unaffected as it does not use the ACPI device status.
