soc/intel/skylake: Use PCI func0 if enabled in device tree

Originally, if a devfn0 device was physically present, it would be
swapped with the next enabled device from the device tree.  This would
result in the WiFi chip not showing up in ACPI SSDT.  We should check
to see if the original device is enabled in the device tree before
looking for the next device to swap into its place.

BUG=b:122327852
TEST=the WiFi chip ACPI wake resource is now present SSDT:

Scope (_SB.PCI0.RP01)
        {
            Device (WIFI)
            {
                Name (_UID, Zero)  // _UID: Unique ID
                Name (_DDN, "Intel WiFi")  // _DDN: DOS Device Name
                Name (_ADR, 0x00000000)  // _ADR: Address
                Name (_PRW, Package (0x02)  // _PRW: Power Resources for Wake
                {
                    0x27,
                    0x03
                })
            }
        }

localhost ~ # cat /proc/acpi/wakeup
    Device  S-state   Status   Sysfs node
    ...
    WIFI      S3    *disabled  pci:0000:01:00.0
    ...
    localhost ~ #
