wlan: Support both Proprietary and Open Source driver
The prima WLAN driver has historicially been built as a Proprietary
DLKM, but we want support building it as an Open Source DLKM as well.
Update the makefiles so that the same makefiles can be used by both
the Proprietary and the Open Source drivers.
