WoW hasn't been tested or verified with ath9k using AR9280 at all, so we
don't know what is missing in ath9k to handle the chip's peculiarities.

If AR9280 is used, getting support for WoW would be difficult. AR9462 has
been through internal test-cycles for WoW, so it seems a more sensible choice.

But, the AR9002-specific code can be retained in the driver if RH needs it.
