[PATCH] ath5k: Clean up eeprom parsing and add missing calibration data

[Felix Fietkau <nbd@openwrt.org>]

This patch brings the ath5k eeprom parsing code in sync with the work
done on ath_info by Nick Kossifidis and integrates the missing parts
based on the code of the Atheros Legacy HAL release.
