ath10k: fix rssi and rate reporting
RSSI and RATES fields are valid only when START_VALID
bit is set. So, in current implementation we have to
remember/caclulate them when START_VALID and report the same
when only END_VALID is set.
Currently during heavy traffic we could have:
- 10 packets with START_VALID - correct RSSI and RATES
- 10 packets with END_VALID
- 10 packets with START_VALID - correct RSSI and RATES
- 10 packets with END_VALID
...
Next using monitor interface we will see:
- 10 packets with correct rssi/rates
- 10 packets with rssi=-95/rate=6Mbps

Kernel panic - not syncing: Fatal exception
Jason's analysis:
"The GCC 4.8.1 compiler will not do the for-loop till scat_entries, instead,
it only run one round loop. This may be caused by that the GCC 4.8.1 thought
that the scat_list only have one item and then no need to do full iteration,
but this is simply wrong by looking at the assebly code. This will cause the sg
buffer not get set when scat_entries > 1 and thus lead to kernel panic.
Note: This issue not observed with GCC 4.7.2, only found on the GCC 4.8.1)"
Fix this by using the normal [0] style for defining unknown number of list
entries following the struct. This also fixes corruption with scat_q_depth, which
was mistankely added to the end of struct and overwritten if there were more
than item in the scat list.

ath10k: remove pci completion list
One of the premises was to guarantee serialized
completion handling for upper layers
(HTC/WMI/HTT). Since quite some time now it is no
longer necessary.
The other premise was to batch up tx/rx
completions to take advantage of hot caches.
However frame tx/rx completion indications come in
on a single pipe already so they are already
batched up. More meaningful batching is done in
HTT itself.
This means PCI completion is no longer necessary
to keep around. It just wastes memory, cycles and
SLOC.

ath10k: bypass htc for htt tx path
Going through full htc tx path for htt tx is a
waste of resources. By skipping it it's possible
to easily submit scatter-gather to the pci hif for
reduced host cpu load and improved performance.
The new approach uses dma pool to store the
following metadata for each tx request:
* msdu fragment list
* htc header
* htt tx command
The htt tx command contains a msdu prefetch.
Instead of copying it original mapped msdu address
is used to submit a second scatter-gather item to
hif to make a complete htt tx command.
The htt tx command itself hands over dma mapped
pointers to msdus and completion of the command
itself doesn't mean the frame has been sent and
can be unmapped/freed. This is why htc tx
completion is skipped for htt tx as all tx related
resources are freed upon htt tx completion
indication event (which also implicitly means htt
tx command itself was completed).
Since now each htt tx request effectively consists
of 2 copy engine items CE_HTT_H2T_MSG_SRC_NENTRIES
is updated to allow maximum of
TARGET_10X_NUM_MSDU_DESC msdus being queued. This
keeps the tx path resource management simple.

For PCI support, rx_conf is not touched directly. Instead, get_hw_reg is
used to abstract between receive_config (for PCI) and rx_conf (for USB).
This was tested on a 10ec:8176 Realtek RTL8188CE (according to the

cfg80211: regulatory: introduce NL80211_RRF_AUTO_BW rule flag
Introduce NL80211_RRF_AUTO_BW rule flag. If this flag set
maximum available bandwidth should be calculated base on
contiguous rules and wider channels will be allowed to cross
multiple contiguous/overlapping frequency ranges.
In case of old kernels maximum bandwidth from regulatory
rule will be used, while there is no NL80211_RRF_AUTO_BW flag.
This fixes the previous commit
