Subject: [PATCH -next] wireless: TI wlxxx depends on MAC80211

From: Randy Dunlap <rdunlap@...otime.net>

wl12xx build fails with many undefined symbol errors when MAC80211
and CFG80211 are not enabled, so make WLCORE and WL12XX depend
on MAC80211 (which already depends on CFG80211).

Here are a few of the many build errors:
