[RFC] ath9k: update hw configuration for virtual wiphys

["Luis R. Rodriguez" <lrodriguez@atheros.com>]

ath9k supports its own virtual wiphys. The hardware code
relies on the ieee80211_hw for the present interface but
with recent changes introduced the common->hw was never
updated and is required for virtual wiphys.

Jouni, it seems this the right place for this, do you agree?
