devices: add support for declaring compatible matched devices

Browse source 
Some device have embedded wifi card that are not connected with usb or
internall with pci. Such device have fake device_id and only the
vendor_id actually reflect something real but internally they don't have
any id and are just matched by the node compatible binding in DT.

We currently match this with a big if-else to match the single devices
but this can be improved and be matched directly in devices.txt

Rework this so that we can drop the big if-else and move the matching
to devices.txt

When a device is matched using compatible in iwinfo the hardware will be
flagged as embedded and won't print empty ids.

Update devices.txt by migrating all the compatible matching device from
fake id to compatible matching.
