[PATCH] ath6kl: force building as a module

[Kalle Valo <kvalo@qca.qualcomm.com>]

Stephen reported that ath6kl fails if both sdio and usb are built
into the kernel:

ath6kl/cfg80211.c:27:1: error: expected ')' before 'KBUILD_MODNAME'
ath6kl/cfg80211.c:27:1: error: 'KBUILD_MODNAME' undeclared here (not in a function)
ath6kl/cfg80211.c:27:1: error: expected ',' or ';' before string constant

As a temporary fix make ath6kl build only as a module. This will be reverted
once a separate ath6kl core module is implemented which will fix this
properly.
