ath9k: introduce ath9k_hw_get_scaled_power helper

The computation of the scaled power value in

that code into a helper function and use that

varies between the different files.

In eeprom_def.c and in ar9003_eeprom.c the value

rt2800: initialize queues before giving up due to DMA error

Don't immediately abort .start if DMA is busy before we
initialize the queues. Some drivers do not deinitialize
queues properly and we would fail to take over after them.

This behaviour is consistent with legacy driver.
