This patch allows the pm-qos value to be user configurable by making it as
a module parameter.This will help our customers to configure the pm-qos
value according to the effect in throughput due to the DMA latency problem
which was observed in Intel Pinetrail platforms.
	The tested value of '55' will be filled as the default
pm-qos-value incase the user does not specifies pm-qos value as a
module parameter.
example usage: sudo modprobe ath9k pmqos=65

The Queue names were incorrectly copied from the legacy drivers,
as a result the queue names were inversed to what was expected.

This renames the queues using this mapping:
	QID_AC_BK -> QID_AC_VO (priority 0)
	QID_AC_BE -> QID_AC_VI (priority 1)
	QID_AC_VI -> QID_AC_BE (priority 2)
	QID_AC_VO -> QID_AC_BK (priority 3)

Note that this was a naming problem only, which didn't affect
the assignment of frames to their respective queues.

As part of the queue refactoring, change the queue callback
function names to have 3 different actions: start, kick & stop.

We can now also remove the STATE_RADIO_RX_ON/STATE_RADIO_RX_OFF
device_state flags, and replace the usage with using the
start_queue/stop_queue callback functions.
This streamlines the RX queue handling to the
similar approach as all other queues.

As part of the queue refactoring, we now introduce
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
refactor the queue control inside rt2x00lib).

Commit 02044643 "Check for specific changed
flags when updating the erp config" changed the way in which a new beacon
interval gets handled. However, due to a bug in rt2800usb and rt2800pci the
beacon interval was reset during each scan, thus causing problems in AdHoc
mode.

Fix this by not cleaning up the beacon interval when killing the beacon queue
but just prevent the device from sending out beacons.

Recent changes to the TX-done code of rt2x00 resulted in TX-ed frames not
being returned to mac80211 in the original state, and therefore with
insufficient headroom for re-transmissions.

Fix this by reverting the changes done and by ensuring we remove the inserted
L2pad by moving the header backwards instead of the data forwards.

At the same time also make sure that the rt2x00queue_remove_l2pad will not
move any memory when a frame has no data at all.
