Add "Not Wired" option for OPTICS_CONFIG_MODE attrs

For Swift systems obus1 is not wired to anything. This is causing
issues when we attempt to enable the link. If we set it to NOT_WIRED
then we should avoid the problem we are seeing currently where obus1
is having the NV link enabled which is getting parity errors as soon
as we enabled the obus.
