    ramips: limit 5GHz channels for RAVPower RP-WD009
    
    When selecting a channel below 100 on the 5GHz radio, the channel will
    be detected as busy all the time.
    
    Survey data from wlan1
            frequency:                      5240 MHz [in use]
            channel active time:            165729 ms
            channel busy time:              158704 ms
            channel transmit time:          0 ms
    
    Channels 100 and above work fine:
    
    Survey data from wlan1
            frequency:                      5500 MHz
            channel active time:            133000 ms
            channel busy time:              21090 ms
            channel transmit time:          0 ms
    
    Limit the available channels, so users do not have the impression
    their device is broken.
