Martin Blumenstingl a20616863d 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).

[add ath9k caldata mac address patcher]
[fixes DGN3500 wifi mac]
[fixes BTHOMEHUBV3A wifi mac]
[set invalid mac for BTHOMEHUB2B, FRITZ3370, FRITZ7320 & FRITZ7360SL to restore previous random mac behavior]
