ath9k: introduce ath9k_hw_get_scaled_power helper
The computation of the scaled power value in various eeprom files uses identical code. Move that code into a helper function and use that instead of code duplication. Signed-off-by: Gabor Juhos <juhosg@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
