qca61x4 uses the vdev param as a sole sufficient configuration
for txbf while qca99x0 enables txbf during peer assoc by
combining the vdev param value with peer assoc's vht capabilities

This patch gets the appropriate txbf configuration scheme
before passing the wmi command to enable the same in the firmware.

10.4 firmware swba event payload has space to accommodate upto
512 client traffic indication info & one p2p noa descriptor.
It's is not matching with exiting swba event format defined for
non 10.4 firmware. Non 10.4 firmware swba event format is designed
to support only upto only 128 client and four p2p notice of absence
descriptor.

following changes are done in this patch to enable ath10k to handle
10.4 firmware swba event,

 - link generic ath10k_wmi_event_host_swba() to handle 10.4 swba
   event in 10.4 wmi rx handler.

 - add 10.4 specific swba event structure wmi_10_4_host_swba_event.

 - new function ath10k_wmi_10_4_op_pull_swba_ev() to parse
   10.4 swba event.

 - increase tim_bitmap[] size in ath10k_vif to 64 to hold 512 station
   power save state.

Due to 512 client support in 10.4 firmware, size of tim ie is going
to be slightly higher than non 10.4 firmware. So, size of tim_bitmap
what is carried in swba event from 10.4 firmware is bit higher.

The only bottle neck to reuse existing swba handler
ath10k_wmi_event_host_swba() for 10.4 is that code designed to deal
with fixed size tim bitmap(ie, tim_info[].tim_bitmap in wmi_swba_ev_arg).
This patch removes such size limitation and makes it more suitable
to handle swba event which has different size tim bitmap.

All existing swba event parsing functions are changed to adapt this
change. Actual support to handle 10.4 swba event is added in next patch.
Only preparation is made in this patch.

WLAN survey data provides several informative values on each channels
such as noise, active time, transmit time, and etc.
Regarding the channel activity time data, it is reported from firmware
in different form which is number of cycles instead of time itself.
Hence host driver converts it to time unit by dividing it by clock rate
that is used at baseband MAC.

Using difference clock rate from that actual HW is using will result in
inaccurate survey data. For instance, channel active time can be reported
with bigger than 150ms even though we set Dwell time to 150ms.
Therefore set the clock rate to 88000 (88 MHz) which is ath10k baseband
MAC is using.

This improves chances of getting onto a foreign
channel and thus makes P2P a bit more reliable.

Without scan burst it was possible for firmware to
not switch to foreign channel resulting in "failed
to switch to channel for roc scan" warning. This
would also effectively fail some offchan tx
requests and lead to P2P find/connect taking
longer. This could be observed when other vifs
were running/busy, e.g. with P2P GO.
