kernel: mac80211: disable ath9k bands via device tree
These properties allow overriding the settings from the EEPROM which indicate whether a band is enabled or not. Setting this property is only needed when the RF circuit does not support the 2.4GHz or 5GHz band while it is enabled nevertheless in the EEPROM. These patches will be replaced with a future upstream version which will introduces an ieee80211 device tree property to disable bands.
