This patch contains the following cleanups:
- remove all the module trick code and build af9005-remote always
into the af9005 module
- make needlessly global code static
- #if 0 unused functions
One might say that always including af9005-remote into the af9005 module
might cause needless bloat, but the fun fact is that altogether the
af9005 module becomes *smaller* (dvb-usb-af9005.ko goes down from 41884
to 41244 bytes in the configuration I tested) despite *additionally*
containing af9005-remote...
