ipq40xx: limit available radio channels for GL.iNet GL-B2200

The PCIe and built-in 5GHZ radios are meant to operate on different frequency bands. The hardware enforces this via RF filters. Add this information to allow software enforcing it as well. Credits to Piotr Dymacz for the invaluable help. Signed-off-by: Enrico Mioso <[email protected]>
