lantiq: use ath9k device tree bindings binding/owl-loader
This moves the extraction of the eeprom/calibration data to a hotplug firmware script. Additionally it modifies all .dts to configure ath9k directly from within the .dts. The owl-loader approach enables support on devices with exotic eeprom data locations (such as unaligned positions on the flash or data inside an UBI volume).
