rt2x00: Merge rt2x00ht.c contents in other files.
The two functions that are in rt2x00ht.c can be much better placed closer to the places where the call-sites of these functions are (one in rt2x00config.c and one in rt2x00queue.c) allowing us to make these functions static. Also, conditional compilations doesn't seem to be necessary anymore as 802.11n support is quite common nowadays. This makes the code a bit easier readable and searchable.
