Michal Kazior 767d34fc67 ath10k: remove DMA mapping wrappers 
There's no real benefit from using them. DMA-API
already provides debugging. Some skbuffs are
already mapped directly with DMA-API since wrapper
arguments were insufficient and extending them
would be pointless.

*
* I know of no way of getting nullfunc frames that contain
* sleep transition from connected stations - these do not
* seem to be sent from the target to the host. There also
* doesn't seem to be a dedicated event for that. So the
* only way left to do this would be to read tim_bitmap
* during SWBA.
*
* We could probably try using tim_bitmap from SWBA to tell
* mac80211 which stations are asleep and which are not. The
* problem here is calling mac80211 functions so many times
* could take too long and make us miss the time to submit
* the beacon to the target.
*
* So as a workaround we try to extend the TIM IE if there
* is unicast buffered for stations with aid > 7 and fill it
* in ourselves.
