ath9k: Add support for Adaptive Power Management
This feature is to mitigate the problem of certain 3 stream chips that exceed the PCIe power requirements.An EEPROM flag controls which chips have APM enabled which is basically read from miscellaneous configuration element of the EEPROM header. This workaround will reduce power consumption by using 2 Tx chains for Single and Double stream rates (5 GHz only).All self generated frames (regardless of rate) are sent on 2 chains when this feature is enabled(Chip Limitation).
