the code that sets the PAPRD rate masks to use only either the HT20 mask

even when configured for HT40, and the operating channel mode does not
affect PAPRD operation.
The register for the HT40 rate mask is applied as a mask on top of the
other registers to selectively disable PAPRD for specific rates on HT40
packets only.
This patch changes the code back to the old behavior which matches the
intended use of these registers. While with current cards this should not
make any practical difference (according to Atheros, the HT20 and HT40
mask should always be equal), it is more correct that way, and maybe
the HT40 mask will be used for some rare corner cases in the future.

The old survey implementation was broken and returned nonsense data.

Clear cycle counters and survey data on reset. Since the cycle counters easily
overflow it's better to keep a local version of collected survey data (in ms
resolution, instead of clockrate) and update this every time survey is
retrieved. If survey is retrieved often enough to avoid cycle counter overflows
this works fine, otherwise we could update survey more often, like ath9k does.
Still only the survey for the current channel is kept.

3 queue commands: start, kick, stop.

 - Start: will enable a queue, for TX this will
   not mean anything, while for beacons and RX
   this will update the registers to enable the queue.
 - Kick: This will kick all pending frames to
   the hardware. This is needed for the TX queue
   to push all frames to the HW after the queue
   has been started
 - Stop: This will stop the queue in the hardware,
   and cancel any pending work (So this doesn't
   mean the queue is empty after a stop!).

Move all code from the drivers into the appropriate
functions, and link those calls to the old rt2x00lib
callback functions (we will fix this later when we

flags when updating the erp config" changed the way in which a new beacon

Fix this by not cleaning up the beacon interval when killing the beacon queue
