ipq-wifi: remove packaged BDF-s for MikroTik devices

Since we now provide the BDF-s for MikroTik IPQ40xx devices on the fly,
there is noneed to include package and ship them like we do now.

This also resolves the performance issues that happen as MikroTik
changes the boards and ships them under the same revision but they
actually ship with and require a different BDF.
