Quick analysis shows I missed ATH9K_HTC. It is not sub-module for ATH9K as I assumed
by mistake, but independent module. Fix follows.

Subject: [PATCH] ath9k: Fix Kconfig for ATH9K_HTC
Ath9k consists of 2 different sub-modules: ATH9K and ATH9K_HTC.
Both uses common Atheros code from ath.ko and need ATH_COMMON.
However, while ATH9K selects ATH_COMMON, ATH9K_HTC does not.
As result, if ATH9K_HTC is the only Atheros card selected, compilation fails with
unresolved symbols.
This patch moves ATH_COMMON selection to the common part for both
ATH9K and ATH9K_HTC
