Enable the "Content" After Beacon queue and utilize it to send
any buffered frames for power-saving clients.

* Write next beacon timer even on AP mode since without this we get
 no beacons + ath9k does it too.  Docs say that we must write 0 on
 this register on AP mode to start TSF increment, we do both to be
 on the safe side.

 * Fix num_tx_pending function, we never read the register :P that's
 why we got all those "beacon queue 7 didn't stop messages".

 * Put full prioriy on beacon queue, lock all queues with lower
 priority using the arblock and also bypass any arblock by seting
 the arblock ignore flag.

 * For the CAB queue (do we need this thing ?, it seems crap) since
 it's supposed to fire up after each beacon (we don't use it on driver
 part, ath9k/MadWiFi does), don't make it DBA gated but instead make
 it fire after each beacon by using the beacon sent gated flag.

 * Increase bmiss threshold to 10, that's what we used on MadWiFi for
 a long time. Also when we have pending frames on the beacon queue (we
 got a beacon that didn't make it on the air) it's more likely that
 the beacon queue never started, probably due to faulty DBA setting,
 so change that "beacon queue didn't stop" message.

 Tested this with AP mode and IBSS mode and seems to work fine ;-)

* Sync qcu.c with legacy-hal
* Add some more comments
* Set QCU mask to save power (QCU mask controls which QCUs are attached
  to each DCU, we do a 1:1 mapping)

TODO: Use max QCU from EEPROM, further sync with legacy-hal and sam's
hal and a few more minor fixes.

I think after this we are ready to implement WME on the driver
part. Anyone interested ?

*Properly get/set all available ISR/IMR values and review common/uncommon bits
*Better handling of per-txq interrupts (we can now resolve what q is generating
 each interrupt -this will help in debuging wme later)
*Some minor updates from legacy-hal
*Properly handle RXNOFRM and TXNOFRM interrupt masking (even when we don't set
 them on IMR they keep showing up, so we disable them by zeroing AR5K_RXNOFRM
 and AR5K_TXNOFRM registers). This doesn't exist on legacy-hal but i've tested
 it on various cards and it works fine.

 * Update registers
 * Update SREV values and add some PHY srevs
 * Prepare ath5k.h for newer radios etc

 Thanks to Atheros 's HAL source we now know for sure how many parts we have
 and what their SREV values are. We also have some updates on registers. Prepare
 ath5k for some major updates ;-)

 My previous mail had 2 more patches following (git log misusage), sorry for double
 posting ;-(

 * No code changes...

 * Split hw.c to multiple files for better maintenance and add some documentation on each file
   code is going to grow soon (eeprom.c for example is going to get much stuff currently developed
   on ath_info) so it's better this way.

 * Rename following functions to maintain naming scheme:

     ah_setup_xtx_desc -> ah_setup_mrr_tx_desc
     (Because xtx doesn't say much, it's actually
     a multi-rate-retry tx descriptor)

     ath5k_hw_put_tx/rx_buf - > ath5k_hw_set_tx/rxdp
     ath5k_hw_get_tx/rx_buf -> ath5k_hw_get_tx/rxdp
     (We don't put any "buf" we set descriptor pointers on hw)

     ath5k_hw_tx_start -> ath5k_hw_start_tx_dma
     ath5k_hw_start_rx -> ath5k_hw_start_rx_dma
     ath5k_hw_stop_pcu_recv -> ath5k_hw_stop_rx_pcu
     (It's easier this way to identify them, we also
     have ath5k_hw_start_rx_pcu which completes the
     set)

     ath5k_hw_set_intr -> ath5k_hw_set_imr
     (As in get_isr we set imr here, not "intr")

  * Move ath5k_hw_setup_rx_desc on ah->ah_setup_rx_desc so we can
    include support for different rx descriptors in the future

  * Further cleanups so that checkpatch doesn't complain
    (only some > 80 col warnings for eeprom.h and reg.h as usual
    due to comments)

  Tested on 5211 and 5213 cards and works ok.
