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).
