Adding configration to disable ip address as a requirement Fixes: #13399

[PlanetJ]

Description:

A change to the asuswrt device tracker requires a device to have an ip address. In AP mode its possible for all of the detection methods to not provide an ip address. The new config option allows for the old (and working) functionality to be restored by no requiring an ip address. This is more specific to devices in ap mode. Default value True.
