ath5k: Switch from read-and-clear to write-to-clear method when handling PISR/SISR registers
Since card has 12 tx queues and we want to keep track of the interrupts
per queue we can't fit all these interrupt bits on a single register.
So we have 5 registers, the primary interrupt status register (PISR) and
the 4 secondary interupt status registers (SISRs).
In order to be able to read them all at once (atomic operation) Atheros
introduced the Read-And-Clear registers to make things easier. So when
reading RAC_PISR register, hw does a read on PISR and all SISRs, returns
the value of PISR, copies all SISR values to their shadow copies (RAC_SISRx)
and clears PISR and SISRs. This saves us from reading PISR/SISRs in a sequence.
So far we 've used this approach and MadWiFi/Windows driver etc also used it
for years.
It turns out this operation is not atomic after all (at least not on all cards)
That means it's possible to loose some interrupts because they came after the
copy step and hw cleared them on the clean step !
That's probably the reason we got missed beacons, got stuck queues etc and
couldn't figure out what was going on.
With this patch we switch from RaC operation to an alternative method (that
makes more sense IMHO anyway, I just chose to be on the safe side so far).
Instead of reading RAC registers, we read the normal PISR/SISR registers and
clear any bits we got by writing them back on the register. This will clear only
the bits we got on our read step and leave any new bits unaffected (at least
that's what docs say). So if any new interrupts come up we won't miss it.
I've tested this with an AR5213 and an AR2425 and it seems O.K.
Many thanks to Adrian Chadd for debuging this and reviewing the patch !

brcm80211: fmac: simplify the brcmf_sdioh_request_buffer() function
The function is only called with sk_buff parameter being non-zero so
the prototype does not need to support passing a char buffer any longer.
When the function is called with a NULL sk_buff parameter it returns
-EINVAL now.

ath9k_hw: Fix minimum CTL power for each runtime mode
The conformance test limits (CTL) for each regulatory domains
(FCC/ETSI/MKK) are programmed for each runtime modes (11B,11G,
HT20 and HT40) in EEPROM. The lowest ctledge power value of a
particular running mode should not be used while computing
ctledge power for a different running mode.(i.e 11G's min ctledge
power should not be used while computing ctledge power for HT20).
Currently, the code does not handle this properly which would
result in incorrect txpowers in certain cases. So reset the
twiceMaxEdgePower to the default while computing min ctlegepower
for every mode.

ath9k: improve ath_tx_aggr_stop to avoid TID stuck in cleanup state
When tx agg is being stopped TID is flushed using ath_tx_flush_tid. It
is possible that ath_tx_flush_tid completelly flushes TID (if all
packets in this TID have already been retried). If this happened
ath_tx_aggr_stop would leave TID in cleanup state permanently.
Fix this by making ath_tx_flush_tid remove AGGR_ADDBA_COMPLETE and
AGGR_CLEANUP flags from TID status if TID is empty.
